Edge of Craving (Primal Instinct #0.5)

Since the moment he'd first laid eyes on Alia Buchanan, the warrior known only as Rhys had been obsessed with her. She consumed his waking moments. Tormented his dreams. But, as one of the few remaining descendants of a European dragon clan, Rhys knew there could never be a future for a monster like him...with an angel like Alia. Until her father is murdered and Alia's life is in mortal danger. Now, Alia and Rhys must unite to find some ancient crosses that hold an unknown power before their enemies do. And once those are in hand, Rhys must figure out what to do with them...and his forbidden attraction to the women he'd sworn to protect.
