A brazen, methodical killer strikes on New Year’s Eve and LAPD detective Renée Ballard and Harry Bosch must join forces to find justice for the victim in a city scarred by fear and social unrest.

There’s chaos in Hollywood at the end of the New Year’s Eve countdown. Working her graveyard shift, LAPD detective Renée Ballard waits out the traditional rain of lead as hundreds of revelers shoot their guns into the air. Only minutes after midnight, Ballard 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.
 
Ballard quickly concludes that the deadly bullet could not have fallen from the sky and that it is linked to another unsolved murder—a case at one time worked by Detective Harry Bosch. At the same time, Ballard hunts a fiendish pair of serial rapists, the Midnight Men, who have been terrorizing women and leaving no trace.
 
Determined to solve both cases, Ballard feels like she is constantly running uphill in a police department indelibly changed by the pandemic and recent social unrest. It is a department so hampered by inertia and low morale that Ballard must go outside to the one detective she can count on: Harry Bosch. But as the two inexorable detectives work together to find out where old and new cases intersect, they must constantly look over their shoulders. The brutal predators they are tracking are ready to kill to keep their secrets hidden.
 
Unfolding with unstoppable drive and nail-biting intrigue, The Dark Hours shows that “relentless on their own, Ballard’s and Bosch’s combined skills…could be combustible” (Los Angeles Times).

Harry Bosch teams up with LAPD Detective Renée Ballard in the new novel from #1 New York Times bestselling author Michael Connelly.

Detective Renée Ballard is working the night beat--known in LAPD slang as "the late show"--and returns to Hollywood Station in the early hours to find a stranger rifling through old file cabinets. The intruder is retired detective Harry Bosch, working a cold case that has gotten under his skin.

Ballard can't let him go through department records, but when he leaves, she looks into the case herself and feels a deep tug of empathy and anger. She has never been the kind of cop who leaves the job behind at the end of her shift--and she wants in.

The murder, unsolved, was of fifteen-year-old Daisy Clayton, a runaway on the streets of Hollywood who was brutally killed, her body left in a dumpster like so much trash. Now Ballard joins forces with Bosch to find out what happened to Daisy, and to finally bring her killer to justice. Along the way, the two detectives forge a fragile trust, but this new partnership is put to the test when the case takes an unexpected and dangerous turn.

Dark Sacred Night for the first time brings together these two powerhouse detectives in a riveting story that unfolds with furious momentum. And it shows once more why "there's no doubt Connelly is a master of crime fiction" (Associated Press).
