They've loved each other in a thousand lifetimes. They've killed each other in every one.

Evelyn can remember all her past lives. She can also remember that in every single one, she’s been murdered before her eighteenth birthday by Arden, a supernatural being linked to her soul. The problem is that she’s quite fond of the life she’s in now, and her little sister needs her in order to stay alive. If Evelyn wants to save her sister, she’ll have to find the centuries-old devil who hunts her through each life before they find her first, figure out why she’s being hunted and finally break their curse, and try not to fall in love . . . again.
