Dr. Adam Cassidy knew two things: life isn't easy and fate's a bitch.

Adam's last mission cost him an eye, his memory, and any chance of staying with his military brothers-in-arms on Guardian's Alpha Team. He'd scraped together the remnants of his life. He'd refined, rebuilt and pushed on alone, while every night, sleep tortured him with the fleeting memory of the warm, welcome press of the soft breasts and lips of a faceless, nameless woman.

Keelee Marshall knew all about loss. She couldn't forget their brief nights of passion—but Adam had. The man she loved beyond reason had disappeared on the battlefields of Afghanistan. It seemed she would have to win his love all over again, and in Adam's ignorance, he was pushing her into the arms of a man she didn't want and a future devoid of romance.

Love can trump the cards fate has dealt both of them. But only if the man holding the cards is a Guardian.
