Excellent.
The Proving Ground (2025) is 8th in the Mickey Haller (Lincoln Lawyer) series. Possibly the best yet.

A courtroom procedural. Mikey with a case against an AI company whose product may have been responsible for the murder of a teenage girl.
It’s set post-Covid. During fires in L.A.
Very contemporary.
… a chatbot told a sixteen-year-old boy that it was okay for him to kill his ex-girlfriend for her disloyalty.
Representing the victim’s family, Mickey’s case explores the mostly unregulated and exploding AI business and the lack of training guardrails.
Along the way he joins up with a journalist named Jack McEvoy (The Poet), who wants to be a fly on the wall during the trial in order to write a book about it.
But Mickey puts him to work going through the mountain of printed discovery materials in the case. McEvoy’s digging ultimately delivers the key witness, a whistleblower who has been too afraid to speak up. The case is fraught with danger because billions are at stake.
