One cop trapped beyond the gate. One partner tearing New York apart to bring her home.
Detective Danny Reagan's life is a ghost. It's been a month since his partner-and the woman he loves-Detective Maria Baker, was swallowed by a gateway into a world of nightmares. Fueled by caffeine and grief, he scours the archives of the NYPD's secret Occult Crimes Division, desperate for a way to rip open the veil and bring her back. But Maria isn't waiting for rescue. In the cold, silent realm known as the Hollow, she's a cop in a precinct of the dead: wounded, hunted, and armed with nothing but grit, a revolver, and a few precious bullets. To survive, she'll have to strike an unholy alliance with a damned mob boss and a creature of living shadow-all while evading a fanatic who wants to use her soul to fuel his dark ascension. As Danny races a doomsday cult to a cursed site that could tear New York apart, he's forced to rely on Maria's brilliant but skeptical twin sister-whose psychic visions may be the only thread connecting the two worlds. The gate is shattered. The line between the living and the dead is bleeding. And to save each other, Danny and Maria may have to sacrifice everything they're fighting for.
