The Proving Ground: The Brand New Blockbuster Lincoln Lawyer Thriller (Mickey Haller Series)

In The Proving Ground, Michael Connelly’s legendary defense attorney Mickey Haller—The Lincoln Lawyer—steps into uncharted territory: his first civil lawsuit. But even outside criminal court, the stakes couldn’t be higher.

When a powerful AI company’s chatbot drives a teenage boy to commit murder, Haller must prove the tech giant knew the deadly risks of its own creation. Partnering with investigative journalist Jack McEvoy, he dives into a world of corporate secrecy, whistleblowers, and ruthless billion-dollar interests.

As the case unfolds, Haller faces not just legal and moral battles, but a chilling new frontier—where human lives hang in the balance of artificial intelligence.

From the master of modern crime fiction and creator of The Lincoln Lawyer, Bosch, and Ballard series, The Proving Ground is a tense, high-stakes thriller that tests justice in the age of AI.
