CITY OF BONES by Michael Connelly
On New Year's Day, a dog finds a bone in the Hollywood Hills - and unearths a murder committed more than twenty years earlier. It's a cold case, but for Detective Harry Bosch, it stirs up memories of his childhood as an orphan. He can't let it go. As the investigation takes Bosch deeper into the past, a beautiful rookie cop bring him alive in the present. No official warning can break them apart - or prepare Bosch for the explosions when the case takes a few hard turns. Suddenly all of L.A. is in an uproar, and Bosch, fighting to keep control, is driven to the brink of an unimaginable decision.
Bosch is back to what he does best, investigating a tough case. Given this case to clear, he must first determine the identity of the discovered bones. That done, he has to dig back into the past and search for the killer. A few false assumptions cost Bosch time, and possibly his job. He makes a decision at the very end of the book that was completely unexpected.
I'm glad I've got the next Bosch book, LOST LIGHT, on the Kindle and ready to read.
