When a teen dies inside an unexplored cave, it's Lani Kimmel's job to bring him out. This is not a pleasant job, but one she can handle as a member of the local fire department and an expert in cave rescues. But the trek into the cave awakens a creature that will push this no-nonsense woman's boundaries of belief and test her newly emerging love for one man.

Rafe Chavez, the new sheriff in this small Texas town, has already staked a claim on Lani. He's a man with a goal in his sights, and he's not letting anything get in his way—until he dreams about an Indian brave who died in that unexplored cave, savaged by a mountain lion. When his dreams cross into reality, Rafe realizes he may be possessed by the Indian's spirit—but the spirit isn't alone and it wants Lani.

Just when Lani's resistance to his erotic persuasion crumbles, Rafe must push her away to protect her from another creature that has also cast its gaze upon her.
