Sandy Sumner is a sheriff with a secret. She's the law in Kasselville, a small town in the fairytale lands, but on nights when she gets the urge to run, Sandy shape-shifts into a predator. That part of her identity poses a threat when Cordelia Bauerstein, a little old lady who ran a pig farm with her brother on the outskirts of town, is found clawed to death on her kitchen floor.

Sandy has 24-hours to find a solid lead or risk losing the case. When the prime suspect, a vagrant wolf who has crossed paths with the victim, comes willingly to the sheriff's office to offer information, the investigation takes an unexpected twist.

What comes to the surface are lies, extortion, and suspects who are not at all what they seem, least of all Sandy and her sidekick Rey. Sandy has kept her secret hidden from everyone, but can she really hope to fool a wolf? Sheriff Sandy Sumner must catch the murderer before she or her friend find themselves on the suspect list.
