The always outstanding Michael Connelly continues to showcase his ability to hit all the crime fiction sub-genres with another wonderful and deeply compelling legal thriller, the new Lincoln Lawyer novel The Proving Ground.

2025 proved to be another outstanding year for acclaimed crime fiction author Michael Connelly, as he not only introduced a new protagonist in his fantastic novel Nightshade (one of my favourite books from the first half of 2025), but he also continued his very entertaining Lincoln Lawyer series with the amazing book, The Proving Ground. Entries in the Lincoln Lawyer series, which has previously featured such awesome books as The Law of Innocence and Resurrection Walk, are always a guaranteed fun read, and I was excited for The Proving Ground for a while, especially as it had a very intriguing plot.

Plot Synopsis:

From #1 New York Times bestselling author Michael Connelly, the Lincoln Lawyer is back with a case against an AI company whose product may have been responsible for the murder of a young girl.

Mickey Haller has moved from criminal to civil court, but murder remains in his sights—in particular, the case of a chatbot encouraging the killing of a teenage girl.

Mickey files a civil lawsuit against the artificial intelligence company responsible for the chatbot and instantly finds himself on the wild frontier of the billion-dollar AI industry. Grappling with a terrifying lack of regulation and data overload, Haller partners with journalist Jack McEvoy. But they are up against mega-forces, and even the bravest whistleblower faces grave danger.

In 1997, IBM’s Deep Blue defeated chess master Garry Kasparov with an unexpected gambit. In a Herculean new match of man vs machine, can Haller pull off a winning play for humanity?

The Proving Ground was a very impressive new novel from Connelly that cleverly set his most entertaining protagonist against a complex real-world issue. Featuring an intense and extremely thought-provoking narrative, The Proving Ground was an addictive read, and I easily got swept up in Connelly’s latest captivating tale.

Connelly pulled together an excellent and clever narrative for The Proving Ground, which quickly throws readers into the legal action and ensures you become engulfed in the complex case. Starting off in the early stages of the case, the author soon introduces you to the latest lawsuit protagonist Mickey Haller is engaged in, suing a major artificial intelligence company, for the encouraging actions of its teenage-focused chatbot. From there you watch as Mickey and his team, which now also features another major Connelly protagonist, Jack McEvoy (from The Poet, The Scarecrow and Fair Warning), attempt to pull together a suitable case of culpability against the company. At the same time, Haller continues to try and find redemption by getting a dying former client released from prison. There is also a dive into the protagonist’s personal life, with a returning love interest once again causing drama in his life after a major real-world natural disaster.

The main plot moves at a fast pace as it focuses on the case, with Mickey dealing with various pitfalls, traps and the machinations of his opponents to try and win the trial. Connelly keeps the intensity of these proceedings at a high boil the entire way through the book, and there is barely a slow moment in The Proving Ground as the protagonist utilises his trademark tricks, unique arguments and clever legal surprises to make ground. The personal nature of the case, as well as the dark implications around AI, make for very dramatic reading, and I honestly could not stop reading The Proving Ground at times, as I was very eager to see how everything came together. Connelly also got the balance right between the main case, and the side stories, with the primary focus on the AI trial proving to be a real winner. Everything comes to a very dramatic head towards the end of the novel where, after the near destruction of Haller’s case, the protagonist engages in his final clever gambit. I really loved how this main trial came together, and while it did end a little too suddenly, I appreciated that Connelly was trying to show some realism in how these sorts of legal cases usually go. I also do think that Connelly could have ditched out the secondary storyline in The Proving Ground, but the attempt to show Haller’s continued growth did ensure it had its place. Overall, this was quite a strong story, and I felt that The Proving Ground was an especially clever addition to the Lincoln Lawyer series.

I quite enjoyed how The Proving Ground came together, and Connelly worked hard to keep the book as captivating and emotionally charged as possible. Featuring a particularly compelling central legal case that dives into a major real-world concern, The Proving Ground was an interesting transition away from the criminal cases that the Lincoln Lawyer series is known for. Indeed, at times The Proving Ground felt more like a legal drama rather than a legal thriller, as there was lack of traditional criminals and high-stakes police elements that Connelly has previously featured. Still, this was very much a highly exciting read, especially in the multiple cleverly constructed courtroom sequences, where the alternating legal strategies, arguments and growing antagonism between the rival lawyers, really dragged in the readers. The excellent central focus on Haller as the first-person perspective protagonist added to the thrill of the plot, as you were constantly there when Haller encountered the many swerves and twists that defined the case. While the tone of The Proving Ground was mostly serious, Connelly did add in some fantastic bursts of humour, which helped to remind the reader that this was a Lincoln Lawyer novel. Much of this involved the over-the-top reactions that Haller’s opponents had to the protagonist’s strategies, but I also chuckled at some fantastic references and clever jokes added in throughout the book, especially those related to AI. This ended up being an accessible standalone novel that will appeal both to general legal thriller enthusiasts, as well as established fans of Connelly, and I think most readers are going to have an outstanding time with this book.

One of my favourite aspects of The Proving Ground was the way that Connelly so effectively and cleverly examined and showcased real-world issues. This primarily involves the central element of artificial intelligence, which the author uses to increase the stakes of the plot and ensure that readers are educated about a complex subject likely to impact them in the future, if it hasn’t already done so. As part of this, Connelly dives into the whole concept of AI and its potential role in society in a notably detailed manner, examining its applications, its potential for harm, and how it will likely change the way people think and interact in the future. This was a very well-balanced and thought-provoking look at a subject many people are worried in real life, and I felt that Connelly did an exceptional job examining it through a contemporary lens in this book. Many of the conclusions about the potential for AI to be abused if not carefully regulated and tailored to its intended audiences was quite troubling, and the reader comes away really thinking about how AI is being used and where it could go from here.

Connelly also takes the opportunity with The Proving Ground to dive into some more recent world issues, notably those occurring in America. The use of Los Angeles as the author’s preferred setting helped with this immensely, and there were some very interesting looks at how the city started to change in 2025. The wildfires that hit the city early this year come into play in a big way during The Proving Ground, especially for some of the secondary storylines, and Connelly tried to capture the authentic fear, anger and despair that these events would have on people caught up in them. This compelling dive into real-world events greatly enhanced the plot of The Proving Ground, and I was very impressed with how Connelly utilised them and portrayed them with his amazing writing.

The final element of The Proving Ground that I want to highlight is the great characters, who Connelly expertly writes and utilises in his compelling story. Most prominent of these is the main point-of-view protagonist, Mickey Haller, whose continues to try to move away from the grubby world of criminal defence by focusing his practice on helping those in need. This redemptive phase of Haller has been ongoing for the last couple of Lincoln Lawyer books, and I’ve enjoyed the character’s attempt at growth in his work, especially as it seems to confuse many of the other characters Haller interacts with, especially his legal opponents. Haller’s attempts to also make up for the mistakes of his past, both in his relationships and his previous defeats, were also well explored in some of The Proving Ground’s secondary storylines, and I very much enjoyed the direction that Connelly continues to take with his high-flying lawyer protagonist.

Aside from Haller, The Proving Ground also follows a compelling group of characters involved with the main case, including the recurring members of Haller’s legal team. While these characters aren’t explored as deeply in this novel as they are on the Netflix adaptation (an adaptation which is cheekily referred to in several books, including The Proving Ground), you still see some elements about how they are going and adapting to Haller’s change in legal clients and focus, with Cisco’s concerns about Haller not needing an investigator for his civil cases being a very interesting point. I also quite enjoyed how Connelly crossed over this novel with another one of his major protagonists by bringing in reporter Jack McEvoy as a major supporting character. McEvoy turned out to be an exceptional part of the book, especially as the concerns with AI really fit this character’s history of writing about controversial and potentially dangerous new technologies. The interaction between Haller and McEvoy, two characters Connelly has developed apart, felt very natural, and I liked how well he fit in as a member of Haller’s team. Throw in some other well-written and emotionally charged characters, including grieving parents, flawed and sometimes hostile witnesses, two entertainingly conniving antagonistic lawyers, and a particularly arrogant CEO, and the cast of The Proving Ground was quite exceptional, and you will love getting drawn into their personal struggles.

Michael Connelly produces another top crime fiction read with the wonderful and highly addictive legal novel, The Proving Ground. An impressive continuation of the always entertaining Lincoln Lawyer series, The Proving Ground was an incredible read, and one that comes very highly recommended. Due to how deeply compelling I found it, The Proving Ground gets a five-star rating from me, and I will be including it on my best of 2025 list later tonight.

Prepare to dive back into the wild world of Jim Butcher’s iconic Dresden Files series with the latest impressive novella, The Law.

Readers of this blog might have noticed that I usually don’t go out of my way to read too many novellas or short stories and instead usually focus on full-length novels and comics. This isn’t so much a deliberate choice as I just prefer whole books I can really sink my teeth into. However, I had to make an exception for the latest Dresden Files novella that Jim Butcher just dropped, as I have been deeply enjoying this epic series.

The Dresden Files are a long running series of urban fantasy novels that follow protagonist Harry Dresden, a wizard who protects the people of Chicago from the magic beings and creatures they don’t even know exist. People may remember that I first got into the Dresden Files back in 2020 when I checked out the 17^th entry in the series, Battle Ground. While I did enter this series late in the game, I still had an outstanding time with Battle Ground and it ended up being one of my top books and audiobooks of 2020. In fact, I enjoyed it so much that I went back and started reading the series from the beginning. So far, I have been able to read the first four Dresden Files novels, Storm Front, Fool Moon, Grave Peril and Summer Knight, all of which have been pretty impressive and captivating reads. This dive into the older novels, plus my lingering enjoyment of Battle Ground, ensured that I was ready and eager for any new Dresden Files content that came my way, and Butcher just delivered with his latest novella, The Law.

Set a month after the events of Battle Ground, The Law sees Harry Dresden and the city of Chicago still recovering from the invasion of the Titan Ethniu and her forces, which resulted in significant destruction. However, Dresden is primarily mourning the tragic death of his love, Karrin Murphy, and even his new responsibilities as lord of a castle and protector of Chicago isn’t enough to keep his mind off his loss. Determined to snap Dresden out of his funk, his friends decide to get him back to basics and introduce him to someone in need of a good investigator.

Enter Maya, a former prostitute turned tutor whose grassroots education company helps to supplement the education of Chicago’s working-class children. Working hard, Maya has managed to turn her tutoring business into a viable, if low-profit, franchise that prioritises helping as many children as possible. However, Maya’s past life is about to come back to haunt her in the form of her former pimp, Tripp Gregory, who initiates a bogus lawsuit against Maya’s company for a ridiculous sum. Unable to afford a lawyer and desperate for help, Maya has no choice but to turn to Chicago’s resident miracle worker, Harry Dresden.

Deciding to the take on the case and hoping to quietly warn Tripp away from Maya, Dresden soon discovers that sometimes the most dangerous opponent is a greedy idiot concerned only for themselves. Worse, Tripp and the case have unexpected connections to the magical world, with dangerous players taking an interest in its outcome. Forced to deal with old and new foes of considerable power, Dresden will need all his wit and will if he is to save Maya’s business and ensure that justice is found.

Well, that has gone a long way to convincing me to check out more novellas in the future. The Law was an epic read that took Butcher’s always outstanding Dresden File’s protagonist on a short, but extremely sweet, adventure. Bringing Butcher’s usual flair and style, while also expanding on events from the last book, The Law was a great read that gets a full five-star rating from me.

Butcher pretty much teaches a master class on how to do a short, concise and captivating story here in The Law as, despite its length, this novella had an impressive and fun narrative that I found to be utterly addictive. Not only does it serve as a great follow up to Battle Ground but it showcases some amazing character work while presenting the protagonist with an intriguing new adventure. The story is so much fun, and I loved how it started as seemingly non-magical job and then morphed into something more dangerous and problematic as Dresden finds that it has connections with the magical world that forces him to deal with some of Chicago’s key players, including some old enemies. Bringing a small but enjoyable amount of legal thriller aspect to the series’ usual urban fantasy crime fiction style, The Law goes in some fantastic directions, as Dresden attempts to placate all the players while also serving his client. There is a great bit of action, a ton of humour, some intriguing revelations, and even some pretty dark moments, which combine extremely well to create quite the impressive narrative. I loved how Butcher wrapped the entire novella up, especially with that one conference scene near the end, and the reader comes away very satisfied and entertained with the entire affair. I cannot emphasise how great this story was, and I was so damn enthralled by it that I nearly finished it in an entire sitting.

One of the things that I particularly liked about The Law is the way that it serves as a bridging novella between Battle Ground and any future entries in the series. Butcher spends a lot of time in this story looking at the aftermath of the previous novel, especially as Battle Ground featured that epic battle that saw Chicago nearly levelled. As such, Butcher packs The Law with a ton of callbacks to the events of the last book, and there is a huge focus on how the various characters are dealing with the aftermath, especially Dresden. There is also a very fascinating look at the rebuilding that is occurring during this time, as well as the current state of the citizenry, many of whom are traumatised or damaged because of a battle most of them couldn’t even fully comprehend. I really appreciated seeing the various figures featured in The Law remembering or trying to understand the events of Battle Ground, whether they are a magical person who lost someone, a normal person who went through hell, or even one of Dresden’s Knights of the Bean, who now bear a dark connection with the protagonist. Some of the details that came out as a result are deeply fascinating, and there are even a few hints about where some potential future storylines might go, such as increased Government awareness of magic (you see evidence of them covering up the events of Battle Ground here), or the increased fear that might lead to humans attacking magic kind in the future. All of these are featured heavily in The Law, and I liked how it was well utilised for the current story, while also showing fans of the series how different the landscape of Chicago will be in the future. I would say that this focus on the aftermath of Battle Ground did make The Law a little less accessible to those readers who haven’t read the latest Dresden Files novel, however, I think that if you are interested in reading this, then you should definitely read Battle Ground first.

I also must talk about the great character work featured in The Law. Despite its shorter length, Butcher manages to fit a decent number of characters in The Law, and there are some impressive character arcs and development that occurs as a result. Naturally, most of this is focused on series protagonist and central point-of-view character, Harry Dresden, who puts on his usual brave face for most of this novella, bringing his usual insights and wicked humour to the new case. However, it soon becomes very apparent that Dresden is still heavily traumatised by the events of Battle Ground, where he lost so much because of the war. Despite his best efforts to hide it, Dresden is a wreck for much of the story, and it was quite confronting and moving to see him experience blackouts and emotional strains due to the tragedies he has experienced. I think that Butcher covered his protagonist’s trauma and grief in a pretty realistic way, and I liked how he tried to use an old-fashioned investigatory case as a coping method for Dresden. It was great to see Dresden going back to his roots as a private investigator after the chaotic and world-altering events of the last few books, and it was interesting to see how much the character’s powers, methods, insights and choices have changed as a result of everything he’s seen. The Law ended up being quite an intense and fantastic look in the recovering Dresden and readers will like seeing his emotional damage, his recovery, and even some of his darker moments that are contained within this excellent novella.

Aside from Dresden, The Law features an excellent array of supporting characters, who bring a lot to the narrative. Butcher made sure to include a combination of new faces and existing characters to fill out the cast, and I had a blast with how they were utilised throughout. Several of the funniest and most interesting recurring figures from the series had substantial roles here, including Bob, Gentleman John Marcone, and even Mab, and each of their appearances and interactions with Dresden were entertaining and fitting with their previous appearances. I enjoyed many of the great new characters that Butcher introduced here. Some of them, including a devilish lawyer with a shrouded identity, may come back in the future, and it will be interesting to see how they are utilised. I also enjoyed main antagonist, Tripp Gregory, mainly because he was so different that Dresden’s usual antagonists. Rather than being a magical creature or a major threat, Tripp is a normal and rather idiotic criminal, who has a surprising power: he’s too stupid to believe in magic and too self-centred to avoid all the trouble Dresden is bringing his way. Dresden’s reactions to having to deal with such a selfish and unusual opponent makes Tripp’s inclusion totally worth it, and I had fun seeing his arc unfold. These characters, and more, were awesome inclusions to The Law, and their unique inputs added a lot the quality and entertainment value of the entire novella.

Finally, a quick note on the audiobook format, which was how I enjoyed The Law. The Law audiobook has a very short run time of just over three hours and is a relatively easy audiobook to get through. I always find myself really getting into Butcher’s excellent stories in this audio format, and this continued here with The Law, and it really helped me enjoy all the novella’s fun and entertaining details. Probably the biggest thing about The Law audiobook was the choice of narrator. I was deeply, deeply shocked when I discovered that long-time Dresden Files voice actor, the legendary James Marsters, wasn’t narrating The Law, and instead Butcher himself took over and voiced the entire thing. Surprisingly, this ended up working out rather well and Butcher turned out to be a pretty competent and enjoyable audiobook narrator. Don’t get me wrong, he’s no James Marsters (a point Butcher makes up-front, after promising Marsters would come back for future novels), but he does a really good job considering his lack of experience. All the characters are given good, distinctive voices that fit their personalities and showcase their emotions and reactions perfectly. His voice for Dresden was particularly good, and Butcher captured his creation’s cocky nature and damaged inner self perfectly. While some of the accents he did were a little iffy, this was an overall fantastic performance from Butcher, and it was fun to see him contribute to his work in this way. The Law audiobook ended up being an excellent and impressive way to enjoy this fantastic story, and it is easy the format I would most strongly recommend.

Jim Butcher continues to expand his epic Dresden Files series in some fantastic ways with the new novella, The Law. Containing a compact, but highly impressive story loaded with some of Butcher’s best characters, The Law proved to be extremely entertaining and a lot of fun to get through. Serving as a perfect follow-up to the major events of the last novel, The Law was an excellent and powerful entry in this long-running series that is a must read for all Dresden Files fans.
