Even in a remote convent, she's unable to escape her past... A decade ago, Sister Maria Delphina did something so terrible, she ran away from her life and joined a convent in a remote area of Spain to spend the rest of her life in penance and quiet contemplation. But she couldn't hide forever. A stranger arrives at the convent door begging Delphina for help with a vampire that has killed his people, kidnapped his father, and settled inside his ancestral home. Delphina tries to refuse...until she finds out the man she fears and hates the most–her father, Dom Calmet–is dying after trying to fight the vampire alone. Delphina agrees to go with the man to help him and Dom Calmet one last time. But inside, she fears that she will not be able to escape from the life of a slayer again.
