Showing Midnight Rescue by Elle Kennedy

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 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 hell hole.

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.
