“The Proving Ground” is Michael Connelly’s eighth outing with Mickey Haller as the primary lead. Mickey is the son of Michael Haller, a famous defense attorney in the Los Angeles area back in the sixties and seventies. Mickey himself has been a somewhat successful criminal defense attorney operating in Los Angeles County. Unlike his father, his office started out in a Lincoln Town Car, and his clients have been primarily drug dealers, gang members, and gangsters.
Mickey’s first ex-wife and first love, Margaret “McFierce” McPherson, has spent most of her professional career as a prosecuting attorney and the mother of his grown daughter, Hayley, recently finished law school herself. His second wife, Lorna Taylor, is his case manager and front-line defense to his clients. She is also married to Mickey’s private investigator, Cisco, who has the uncanny ability to hunt down anybody or anything.
On a nostalgic note, it has been 20 years since Michael Connelly published “The Lincoln Lawyer” which was introduced us to Mickey Haller, the younger half-brother of retired Detective Harry Bosch, Connelly’s long-running detective series. Eight books and two decades later, Mickey stands tall, having built his own legacy in the legal courtroom, his chosen field of battle. And having a very successful Netflix series certainly strengthens that legacy.
Life has certainly changed for Mickey in several ways since his last outing. When “The Proving Ground” begins he has followed his personal commitment to leave his defense practice behind and focus on helping those who need someone to fight for them. This time, he is fighting for Brenda Randolph, who’s teenage daughter was shot and killed by her ex-boyfriend at school, but he’s not suing the boy’s parents. Instead, he’s filing a civil lawsuit against Tidalwaiv Technologies, an artificial company who’s unique chatbot (an app called “Clair”) told the boy that her disloyalty to him made it okay for him to kill her. The argument is that the AI app was not properly tested and lacks the proper guardrails needed to keep its users safe.
Their problem is that Tidalwaiv is worth billions and looking to get bought up by one of the large tech companies, especially one that starts with the letter “M”. However, a bad courtroom decision could destroy the investors chances of reaping the benefits of any potential sale, and the company’s leadership is not afraid to intimidate and scare-off ex-employees who could serve as witnesses against them, as well as destroy any incriminating evidence that would hinder their case.
This time Mickey’s fighting the future, but he’s also not alone. Jack McEvoy, a journalist with three published nonfiction books, and another one of Connelly’s lead characters from previous novels offers to assist Mickey with his case as long as he can write a book about it after the case has been decided in court. Mickey’s not sure about letting Jack join his legal team, even if only temporarily, but he lacks the necessary subject matter expertise involved with the world of AI, and Jack has the knowledge Mickey needs.
In addition, Mickey’s ex-wife and new District Attorney, Maggie McPherson, has come back into his life due to tragedy of her own. The Southern California wildfires took her home and all that she had, leaving her with just her car, her laptop, and the clothes she was wearing. She has currently moved in with Mickey, but she is suffering mentally and emotionally.
As Mickey tries to balance being there for her and preparing for his AI court battle, he gets a call from the daughter of a man he represented many years ago, but lost the case and the father’s been in prison ever since. The daughter insists on seeing him immediately because her father is dying of cancer and she has found the medical needed to potentially set him free.
Then things get even worse when Mickey’s prime witness, a whistleblower, has been scared off from testifying…
Connelly is not shy about taking on serious legal issues. He hinted at the unrestrained dangers of AI in his last Mickey Haller novel and then hits it head on in this one. The world of AI and business development feels a lot like the wild, wild west to many of us trying to understand and use this advanced technology in our work and home lives. This is not an easy subject to deal with, let alone deal with the legalities of such an unregulated industry. Without spoiling anything, I share my absolute appreciation for how he dealt with such a polarizing and cutting-edge subject matter. Kudos, Connelly.
I am sure that it won’t be a surprise to say that there were many things that I loved about this book. With all due respect and love for John Grisham (and I truly love his books), there is nothing better than experiencing Mickey’s courtroom battles – both inside the court and outside the court – with the judge and opposing attorneys. Their back and forth - actions and reactions – are so well delivered in tension packed dialog. As the old Priceline commercials promised – “priceless”.
Connelly moved back and forth from trial preparations, courtroom drama, and personal issues with Maggie in a seamless, smooth, and great storytelling manner. Even with Connelly using Tidalwaiv to represent the evil empire in this book, we still see the influence and impact of AI on the legal system in a very creative and provocative storytelling style that challenges your thinking. The buildup built to a crescendo climax that left you feeling drained, emotionally spent, and frustrated all at the same time. Way to deliver the drama as well as real-world outcomes, Mr. Connelly! Somehow, you seem to be several steps of the game on this one.
As I have described in previous reviews, my personal big three go-to writers for mystery and legal thrillers (in particular order) are David Baldacci, John Grisham, and Michael Connelly. But there’s just something so special about Connelly’s style and storytelling. To me, he’s a master storyteller. Period. End of story. Maybe it’s his many years as a newspaper crime beat writer. I’m sure that’s a big part of it. Either way, his insight into police procedural investigations, courtroom procedures and activities, and city/county government politics is second to none.
With 40 books under his belt, Connelly continues to consistently create strong tension, clever plotting, and well-delivered legal twists and turns. He is a master of characters, setting, and plotline. It’s that simple. Whether he is delivering a detective focused Harry Bosch novel, a Mickey Haller legal novel, or a Jack McEvoy investigative reporter thriller, doesn’t matter. They are all awesome reads. I find it interesting that every one of my Goodreads reviews of his books have been a score of 4 or 5 out of a total of 5 points. I have never scored him less than a 4. That is a pretty amazing mark of great consistency, especially an author with 40 books on his resume.
I am continually impressed with the strong quality that he applies to each one of his books. Connelly is a master narrator, never telling the same story twice, and constantly treating his readers with tight plotting, well-developed characters, and surprising twists that increase the tension and outcomes. I keep making the same statement after finishing each of his novels, and I am making it once more. Like a fine wine or whiskey, Mickey Haller just gets better and better with age. It’s that simple. He’s growing and developing as a character, which make his relationships stronger and even more important than ever. I don’t know how Connelly keeps raising the bar, but he consistently does. He’s just that good...
My only complaint of this book is that it was such a smooth and fast read that it was too dang short! Even at 384 pages, I read it in about 24 hours over the weekend. What was intended to be a slow, immersive read, turned into a suspenseful legal thriller that took my full attention, kept me late, and practically had me yelling at characters in the book! It certainly helps that he’s back to publishing two books a year in 2025 and 2026. I just can’t get enough to feed my fix…
Overall, having read all of Connelly’s books, from the beginning of their stories – Bosch, Haller, Maddie, and Ballard – through their careers, personal growth and development, their struggles and steps back, recoveries, and their natural aging that goes with it. Their lives have been told over 40 years of great storytelling by Connelly, with of course, Bosch’s story arc being the longest. Each character has such an inner-strength to persevere and right the wrongs of society. That’s what makes them so heroic. Their passion for serving justice.
The other thing is that we don’t know how much longer we’ll have the character of Harry Bosch in the book version. In the novels Bosch is aging, fighting cancer, and working hard to leave his make on justice before he leaves this world. It’s safe to say that Harry’s on the backside of his literary life.
I don’t say this to be mean. There may be three, four, or even more Bosch involved novels to come, but it also means they will most likely come to some kind of end for this enduring character who lives the mantra of “Everybody counts or nobody starts”. And even if Harry were to pass on, there will still be Mickey Haller, Renee Ballard, and Maddi Bosch to carry forward his legacy, but for me, that just means that I need to cherish his remaining days in every opportunity that Connelly gives us in future books.
Thank you, Mr. Connelly. “The Proving Ground” is another strong engaging 4.5-star (rounded up to 5) read that again demonstrates your mastery of the storytelling craft. Until next year, I will patiently await your next book…
