Dangerous. Ruthless. Savage. And she's the good guy.

Abby Sinclair had a desperate childhood until she was rescued and adopted by a retired army ranger who molded her into a master of self-defense. Now, she's a cunning and fearless assassin thrust into assignment after dangerous assignment, using everything she has-nerve, resilience, strength, sex-to come out on top. Her only rule: trust no one.
Abby's latest assignment is in Columbia: go undercover and snuff out a dangerous arms dealer act...
