Fifteen-year-old Ben must cope alone when a mysterious sniper begins shooting the big cats in his family's private zoological preserve. A killer stalks the night. The canyon is dark. Pitch dark. It is quiet. Deathly quiet, except for the howl of distant coyotes and the occasional roar of one of the big cats. Fifteen-year-old Ben has been left in charge of the family's California wild animal preserve while his parents are in Africa. Suddenly the silence of the night is broken by screaming peacocks. Someone is out there. Someone with a score to settle. And tonight is only the beginning.
