El Paso, Texas: There have been strange sightings in the foothills of the Franklin Mountains. Hunters and hikers alike have reported seeing a young girl wandering the scrub, accompanied by a pack of coyotes and stray dogs. Rabbits and mule deer have been found mutilated, drained of blood, their throats ripped open.

Meanwhile, Rebecca Carter has been alive for ten days. She awoke on a steel table in a tiled morgue with only two desires: the first, to find her daughter, Moonflower; the second, to sate her gnawing hunger. So far, she has only accomplished the second. Twice. The first time on the outskirts of El Paso, a drunk man who chased her into an alley. The second time, a man who offered her food in return for a service she didn't want to provide. In his cheap motel room, she sees a news report about a young girl roaming the mountain scrub with a pack of dogs. She takes the dead man's car and heads for the mountains.

In Washington, DC, Special Agent Sarah McGrath hears a news report about the sightings of a feral girl, and the disappearance of Rebecca Carter's body. The same Rebecca Carter who was shot dead by McGrath's partner, Marc Donner, moments before he was gunned down by El Paso cops. She thought he'd gone crazy, but now she's not so sure. Even though she knows it's a mistake, she flies from DC to El Paso, looking for answers.

In this breath-taking follow-up to Blood Like Mine, Stuart Neville, "Stephen King's rightful heir" (Will Dean), brings to life the ultimate undead horror: a mother who has been separated from her daughter, and who can stop at nothing to be reunited.
