When smalltime San Diego security consultant Kirbi Mack is hired to track down a former member of a local Indian tribe, the job seems fairly straightforward. The object of her attention? A young man suspected of brazenly robbing the tribal casino. She's asked to find him, but do so quietly-since the matter is a sensitive one within the tribe, and because such casino crimes are best kept out of public awareness.However, things aren't going to stay quiet for long. Kirbi's quarry proves to be a troubled, one-time MMA fighter with a taste for solving his problems with violence, and he's teamed up with an equally troubled older woman. Together the two are cutting an increasingly desperate and deadly swath through the lives of those around them. So as Kirbi continues her investigative pursuit, a stark question begins to take shape in her mind. What happens when the hunter at last brings the beasts to bay?
