Parallel Fire: The Parallel Series, Book 3.5 — Deidre Knight

Anna Draekus has harbored a shadowy secret all her life, one she's spent years concealing from her king and fellow military officers. Anna belongs to an elite, underground guard, charged with protecting the royal family at all costs. But when her superior officer Nevin Daniels uncovers her membership in the clandestine group, she finds herself in treacherous territory. A place where attraction and temptation overrule everything else, including her loyalties. Lieutenant Nevin Daniels can't help but fantasize about his beautiful fellow soldier -- nor can he resist Anna's unselfconscious sensuality. Still, he's her superior officer and maintains a cool reserve, remaining emotionally aloof until a routine patrol changes everything.

When an unexpected incident leaves the pair marooned deep in the backcountry, Nevin's long-restrained desire threatens to grow dangerously unleashed. Especially once ritual mating fever overtakes Nevin, overpowering him--and making him aware of what he's always denied. His intoxicating attraction and need for Anna. Secluded together in the wilderness, and with Nevin in the throes of mating heat, they awaken desperately to each other. Will they enter the primal mating cycle together and bond, no matter the cost? After all, what happens in the back country of Wyoming stays in the backcountry of Wyoming….or does it?
