The Burning Room by Michael Connelly

Harry Bosch is paired with newbie detective Lucia Soto to investigate the murder of mariachi musician Orlando Merced. Merced was shot ten years ago, but only recently died--the bullet had been lodged in his spine since the shooting. Bosch and Soto delve into the original investigation of the case and try to find who would've wanted Merced dead. Bosch also becomes involved in another cold case, the Bonnie Brae fire of 1993, in which nine people lost their lives. Soto was one of the children who survived the fire and, now, having become an LAPD detective, has secretly been looking at the old files to find out who was responsible. The Burning Room shows Connelly is still in top form after all these years, giving the reader an engaging mystery and characters you really care about. It will be published in November.
