In the world of the Immortals, vampires, shape-shifters, and other magical beings exist side-by-side with humans, sometimes benevolently, sometimes violently. The Immortal warriors were born and bred to keep the forces of death-magic at bay, a challenge in a world that has forgotten what the Immortals were for.

Mariah isn't an Immortal—she's a low-level telepath for the paranormal division of the LAPD. Her assignment today is to search out a vampire buried deep beneath a newly renovated vampire club.

When Mariah reaches the club, she senses the vamp's an Old One, an ancient being from the dawn of time. She needs to take him in and turn him over to those up the food chain as quickly as possible, because letting a vamp come too close will drain Mariah of her powers and render her helpless against the death-magic creatures it's her job to pursue.

Cai, who's been in dark sleep since his enemies buried him a few centuries ago, emerges into a brand new world. His rescuer is a beautiful human woman who becomes his only link to understanding this city of metal and concrete, with its rules to keep vampires in check. No more hunting vamps to the death—now vampires are regulated, restricted, all but muzzled.

Mariah seems to understand his distance from the world, because she experiences the same disconnection. Cai hopes to make her his own, but he soon learns that touching her will hurt her more than he can stand. Cai has already lost everyone dear to him and refuses to lose her as well. But when danger comes, the only choices he can make are heartbreaking ones.
