Keira Kelly has settled in at Wild Moon Ranch with handsome Adam Walker, her vampire lover, but her life is not so hot. Not only is Keira still struggling with the Change that will bring her an as yet unknown paranormal power, but Adam's avoiding intimacy and mysteriously growing weak. At least she has Tucker, her 1200-year-old shapeshifting ex-Viking brother, around to help.

When a ranch hand is reported missing and some teens disappear, Keira and Tucker have a heap of unexpected trouble piled on them. There's a lot of weird doing down around Rio Seco, Texas, and after Keira and Tucker stumble across some dangerous clues in an abandoned cemetery, things get even stranger.
