When Eli spots Ashley across a bloody battlefield, he can only steal a moment alone with her. Powerlessness is an emotion new to the angel, but it's one he faces daily when he realizes killing Lucifer in order to free Ashley is out of the question.
'Death' is not a nickname Ashley wants to carry. Being the only one able to stop Lucifer's evil plan is an even worse fate. When she learns her true ancestry, fear that she will succumb to the darkness forces her to dig deep for the strength she will need to win her freedom.
Eli can't stand the pain Lucifer inflicts on the woman he loves, but she is the only one who holds the key to unlock her prison. Until Ashley unleashes her full potential, no one will be safe from Lucifer and the lovers will never be together.
