The Proving Ground

The Brand New Blockbuster Lincoln Lawyer Thriller

By: Michael Connelly

Narrated by: Peter Giles

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.

Another brilliant novel

It dealt with misgivings that people have about AI and it’s unknown unknown. Very thought provoking.

Too short!

This was fantastic as always but has left me wanting more. I devoured it. Fantastic reading and great content

Great as usual

Maybe not the best Lincoln lawyer book, but it has almost everything I love in this series: interesting court facts, unpredictable twists, cool characters. Recommend!

B-r-i-l-l-i-a-n-t!!!

Another stellar novel in the Lincoln Lawyer series. Finished it in 2 days. And my only “complaint” is that it was too short. Didn’t want it to end. I know it has barely been published. Yet here I am impatiently waiting for the next one!

A Fruit for thought

the story takes you as usual with other Lincoln Lawyer stories but this one gets even more interesting as take the attention to questions about generative AI that we have today.
