Wild Cat by Jennifer Ashley

Description

When Diego Escobar assists in what should be a simple task of arresting a trespasser, he comes face-to-face with his first Shifter–the beautiful Cassidy Warden, sister of the Shiftertown leader. Assigned to watch over her, Diego learns more about the lonely, wild Cassidy than it's safe to know.

Diego might be human, but he's virile and darkly handsome, and stirs Cassidy's mating desire, which she thought dead forever. Once the fires begin, nothing and no one can put them out.
