After two years of wrong turns, defense attorney Mickey Haller is back in action. His former colleague Jerry Vincent has been slain and Haller inherits his biggest case yet: defending a Hollywood producer accused of multiple murders. With a key part of the defense's strategy missing, Haller scrambles to prepare for trial- and gets more pressure when he learns that Vincent's killer may be coming for him next. Enter Harry Bosch, who will do whatever it takes to crack the Vincent case, including using Haller as bait. But as danger quickly mounts, these two loners will soon realize that their only chance is to work as a team.
