Sammy is a prep school kid struggling with teen love and bullying. Sara is a medicine man’s daughter, an outcast and a sociopath. The rich girl and the warrior are from different centuries. And yet they coexist. 

Of course, no one believes Sammy because she’s committed to Summerhill Psychiatric Hospital.  But Sara, her doppelgänger, is real.  Sara is slaughtering her way through the American West in the late 1800s.  And Sammy can’t give her doctors a logical explanation for her strange situation.  All she knows is this: only her devotion calms Sara’s bloodlust — until Sammy becomes a killer too.
