Taken (Skin Walkers) by Susan Bliler

Nyree was thriving as the best female Sentry assigned to the Skin Walker teams. Placed on special assignment, she was flattered to have been chosen to train the Keepers who’d just arrived at the Estate. Keepers were different from the Walkers she’d been trained with. Highly aggressive toward females, she found out too late that Keeper aggression was sexual and not a disdain for the female species. Paired with a Keeper, Rohmulus, who clearly despises her, Nyree is shocked that when the Estate comes under attack, Rohm opts to protect her above all others, including himself.

Rohm, like all Keepers has been warned by the Ruling Keeper, Fatal, to keep his hands off the human female assigned to train them. When she is paired with him though, the hunger that he’d been holding at a slow simmer boils over. Taken captive, their captors abuse Nyree to get action from Rohm, and he’ll do whatever it takes to keep Nyree from harm even if it means gifting her a part of his very soul.
