Perfect Revenge by Jane Blythe

This isn’t a Prey sanctioned mission.

Rose Gardner was quietly living the life she fought hard to claim when she’s snatched from her bed in the middle of the night. Waking up in a concrete cell she quickly learns she’s been taken as bait to lure in her brother. Too bad for her captors that her brother doesn’t care what happens to her, which means she’s on her own. If these men think she’s going to cower before them they’re going to be sorely mistaken, because she grew up on a steady diet of pain and suffering and she’s going to find a way to escape or die trying.

Steel is the team leader of Prey Security’s Delta Team, and he’s already led his men into danger once before. It changed everything about them, and now they live in the shadows, too dangerous to be close to anyone. When an opportunity to get revenge on the man who destroyed them comes along there is no way he can’t take advantage of it, the least he owes his men is a chance at vengeance. But the last thing he expected was to find that the fiery redhead he’s holding captive is nothing like they thought she would be.

She’s her own brand of messed up and her demons call to his leaving him in an impossible situation.
