Vic Vargas, a tall, dark, single dad Texas rancher, finds himself facing more than his stubbornly silent son when the chupacabra, a supposedly mythical blood-sucking beast, starts killing his livestock—and stalking the town’s newly returned veterinary assistant, Delaney West, the sensual woman who ran from the altar and broke his heart twelve years earlier. Determined to purge his sizzling memories of her from his all-too-vivid imagination, he seeks her help to get to the bottom of the disturbing animal mutilations, only to have her break through to his sullen son…and rekindle the love he’d thought was lost forever.

But Delaney's refusal to share a terrible secret sends her running straight into the lair of the chupacabra, plunging her back into her worst nightmare, and forcing both she and Vic both to confront the wrongs of the past in order to stay alive for the future they desperately want.
