American travel expert Kiera Morissey is adept at getting in and out of tight spots. But when a deathbed promise brings Kiera back to Draycott Abbey, she meets rugged Scotsman Calan MacKay, and her life is changed forever. For fifteen years, changed by turns to a swift creature of night, Calan has used his deadly strength and speed to protect. But he wakes with bruises on his body and blood on his hands. And Kiera may be the key to getting his life back.
Calan stirs emotions in Kiera that she's never felt before. Getting in and out may be her skill, yet she finds it impossible to leave the abbey until she's unraveled its mysteries, and Calan's dark secret. But will the shadows from the past and an ancient vow of evil threaten the future they may have together?
