Reviews Of THE PROVING GROUND Are Coming In
“Bestseller Connelly crafts a riveting eighth case for attorney Mickey Haller… Connelly effectively dips his toe into topical waters here, touching on adolescent male loneliness and the dangers of AI without skimping on the propulsive plotting he’s known for. Newcomers and series fans alike will find this fast-paced legal procedural intensely satisfying.”
— Publishers Weekly
“The Proving Ground is the most relevant and compelling legal thriller of the decade, and Michael Connelly proves once again that nobody captures courtroom drama and the high-wire act of justice quite like him.”
—Ryan Steck, The Real Book Spy
