Sworn to protect a scenic island meant to be far from the evils of the mainland, Detective Sergeant Stilwell can feel danger closing in. Acting on a tip from a confidential informant, Stilwell and his deputies watch a plane land in the middle of the night at the Airport in the Sky, a remote airstrip in the mountains. A duffel bag of drugs is dropped and the deputies move in, but things quickly go sideways. While Stilwell chases the fleeing pickup man into the mountainside brush, shots are fired on the runway and the plane flies off.
An internal inquiry follows, putting Stilwell on the bench until he is cleared of responsibility for the disastrous operation. While under orders to remain in the sheriff’s substation, he finds in the lost and found a valuable backpack that was never claimed. He traces it to a woman who disappeared while hiking on the island four years ago. But then why was the pack only turned in two months back? Now thoroughly intrigued, he follows the mystery all the way to the LAPD’s Open-Unsolved Unit and Detective Renée Ballard. Ironwood comes out on May 19, 2026.
“One of the best yet from best-selling author Connelly.”
— Booklist starred review
“Michael Connelly writes his bestselling novels in real time, setting them in the year they’re published. His latest, “The Proving Ground,” seems so ripped from the headlines it feels as if he’s writing it as you read it.”
— Colette Bancroft, Tampa Bay Times
“Engrossing… Among Connelly’s strengths: weaving current issues into his superb plots and making even the most complicated subjects understandable. One can’t get more timely than AI, nor more complex. …Connelly’s precise look at the law and his return to Mickey Haller are most welcome.”
— Oline Cogdill, South Florida Sun-Sentinel
“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
The Bosch universe at Amazon continues to expand with a prequel series for MGM+, Bosch: Start of Watch, starring Cameron Monaghan (Shameless) and Omari Hardwick (Power). The premium linear channel and streaming service has greenlighted the offshoot which explores the origin story of Michael Connelly’s detective Harry Bosch, portrayed by Titus Welliver on the original Bosch series and its sequel Bosch: Legacy.
Monaghan will take over the role, playing rookie cop Harry Bosch, with Hardwick portraying his training officer, police veteran Eli Bridges, a new character not in the book mythology. There is no direct source material for Start of Watch since Connelly’s novels do not include a Bosch prequel, though bits and pieces from Harry’s early years are planted in various books in the universe, with Connelly calling the prequel “uncharted character territory.”
