When an angel crashes to earth, her only hope to get back to heaven comes in a form of a demon. When Cielo helped the archangel Michael to overthrow the demons in the battle of Berlin, she hurts her wing and crashes to the ground. When she awakens, she was unable to fly back to heaven and she has to wait until her wing heals. What she didn't bargain on was the identity of her caretaker, a demon named Bane. The longer she stays, the harder it becomes to ignore the powerful pull she feels toward Bane, and falling in love will be the end of her divinity.
