Lust by Moonlight

As a shifter, Mark Guitron is uniquely equipped to search for the devil beast, El Chupacabra, and stop the horrible killings. Hunting one night by moonlight, he spots another wolf whose aura tells him she is also a shifter. When he's visited by an erotic vision of her in human form, he knows he must find her and make her his own. Chloe Hanson is searching for a friend she's convinced is a victim of the devil beast. When she meets Mark, she feels a primal tug that tells her they are meant to be together. As they join forces in the hunt, they soon learn that sex between them feeds a need, rather than slaking it. The multiple orgasms barely satisfy their lust for each other, and as they draw closer to their prey, their fiercest coupling is yet to come.
