From #1 New York Times bestselling author Scott Sigler comes a tale of murder, madness, and an unspeakable evil lurking beneath the streets of San Francisco.

San Francisco homicide inspector Bryan Clauser is losing his mind. How else to explain his dreams, dreams that mirror — with impossible accuracy — gruesome murders drenching the city in blood? How else to explain the feelings these dreams provoke in him? Not disgust, not horror, but excitement.

As Bryan and his longtime partner Pookie' Chang investigate the killings, they learn that things are even stranger than they initially seem. The victims are all enemies of an ostracized teenage boy, a boy gripped by the same violent, prescient dreams that haunt Bryan.

When Bryan and Pookie dig deeper, they uncover disturbing details of a mysterious cult known as “Marie’s Children,” and of San Francisco’s secret history of serial killers, a history that their superiors — from the mayor to the police chief and on down — seem desperate to keep hidden. 

Featuring a dazzlingly plotted mystery and a terrifying descent into a nightmarish underworld -— along with some of the most incredible action scenes ever told and an explosive, gut-wrenching conclusion you won't soon forget — NOCTURNAL is a spectacular outing from one of the horror genre's brightest stars.
