Shay Phillips knows her way around Dark Canyon. She's handy with a gun and can track a wild animal with the best of them. It's humans who usually give her the most trouble. And with a hormonally charged teenage brother to raise--and an admitted weakness for the wrong kind of man-- Shay's got more than her share of challenges. Then there's the matter of murder. As an expert on mountain lions, Shay is skeptical when a local prostitute turns up mauled without a drop of blood near the body.
