Samantha Withers is a troubled 18-year-old, who is desperate to break ties with her overbearing father and escape undeserved blame for her mother's rape and murder. She struggles with her caged inner demons, afraid of the havoc she'll wreak if she gives in to her anger. It begins the night Sam is recruited by a mysterious man named X for a job that may be a little too perfect for her situation: hit man. X can give Sam everything: money, freedom and his sexy employer, Ace. All Sam has to do is become an adversary to society. Sam agrees, justifying it as vigilante work. Through her unorthodox training at Ace's secret base of operations, Sam's strength and skills intensify, as does her "friendship" with X and obsession with Ace, and she learns she's not the only one struggling with personal demons and a haunting past. After her first hit Sam unleashes her demons, transforming into her alter ego, Jinx. Armed with twin pistols and daggers, Jinx has a dark, calloused view on humanity, like her beloved Ace. But Jinx's new world is threatened when her father comes searching for her, demanding she return home. And with each new hit Ace assigns, Jinx unearths new and shocking information pertaining to her mother's death, with evidence pointing to daddy. The revelation leads to a father and daughter reunion neither will soon forget.
