The dark hours / Michael Connelly.

"Has a killer lain dormant for years only to strike again on New Year's Eve? LAPD Detective Renée Ballard and Harry Bosch team up to find justice for an innocent victim in the new thriller from #1 New York Times bestselling author Michael Connelly"-- Provided by publisher.

Hollywood, New Year's Eve. Working her graveyard shift, LAPD Detective Renée Ballard seeks shelter at the end of the countdown to wait out the traditional rain of lead as hundreds of revelers shoot their guns into the air. She is called to a scene where a hardworking auto shop owner has been fatally hit by a bullet in the middle of a crowded street party, and is quick to determine that the deadly bullet could not have fallen from the sky. Ballard's investigation leads her to look into another unsolved murder-- a case at one time worked by Detective Harry Bosch. As old and new cases intersect, the killer who has stayed undetected for so long knows they are coming after him. -- adapted from jacket
