Onset of Darkness (Sworn Protectors #1)
Aubrey Ross
Caitlyn has survived by her wits and daring, deep undercover in enemy territory. When she's sent to search for survivors among the twisted wreckage, the last thing she expects to find is a pureblood prince. Then his strong arms surround her and his bite unleashes longings more intense than anything she's ever known.
With mutual enemies closing in, they form an uneasy alliance and plan the rescue of their captured comrades. They know they can't trust each other, yet each kiss, each fevered caress binds them more closely together.
