The Proving Ground

Mickey Haller - The Lincoln Lawyer - leaves criminal court behind for his first civil lawsuit. But to him, this is still a murder trial.

An AI company's chatbot encouraged a sixteen-year-old boy to kill his ex-girlfriend. Can Haller prove the company knew the dangers of its own creation?

To do so, he turns to Jack McEvoy - a journalist who knows how powerful the coming wave will be - and together they soon uncover a whistleblower in hiding.

As the tech titans try to buy or bully their way out, the scale of their courtroom battle before them becomes clear. Because billions are at stake - along with countless lives - in an all or nothing case, which could change everything...

From the author of the books behind the #1 Netflix show The Lincoln Lawyer, and #1 Amazon Prime series Bosch and Ballard.
