Book 1 of the Infernal Night series. Lord Viper de L'Night believes his sister has been kidnapped by Lady Dominique Toussaint's vampires. He infiltrates her nest and captures the lady in return. When she denies the kidnapping, Viper turns her into his sex slave. He even performs the Ero-X on her—a bonding for breeders—which cannot be reversed. Viper and Dominique were war trained by the same master years ago. Dominique fights but she's drawn to Viper. And he demands submission—something she won't give. When they find who has Viper's sister, they join forces to get her back. If they can learn to trust one another, they just might have a future together.
