UnGuarded (Volume 1)

Guardian angel Selene was so close to becoming an archangel--the supreme of all beings--until she fell in love with Cole, a forbidden dark one. Once she discovers her vampire lover has been kidnapped and the only way to save him is by abandoning her number one priority--Caitlyn, her human charge--there really is only one answer in Selene's mind, even though leaving Caitlyn unguarded will most likely cause Selene to fall from grace. But her choice to save Cole doesn't come without a price...and now Selene is racing against time to not only save her dark lover, but find a way to keep Caitlyn alive as well. With the help of a new vampire ally, Luke, Selene will push her diminishing angel abilities to the point where her very existence lies in the balance. Now threatened with the chance of becoming a fallen angel or even dying, Selene can only pray she'll have enough time--and good grace--to save the ones she loves.
