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 Colombia: Go undercover and snuff out a dangerous arms dealer active in the underground sex trade. But when Abby purposely blows her cover in a last-ditch attempt to free the helpless victims, deadly mercenary Kane Woodland is recruited as back-up. His mission: Get Abby out of that hellhole.

The last thing Kane expects is to feel a primal attraction for Abby. But when she convinces him to join her on her perilous mission, their newfound passion could put the lives of their whole team at risk.
