Time is running out for Luce and Daniel in Lauren Kate's fourth and final Fallen novel. To stop Lucifer from erasing the past, they must find the place where the angels fell to earth. With dark forces after them, they face an epic battle that will end with lifeless bodies...and angel dust. Great sacrifices are made, and hearts are destroyed.

Throughout time, Luce and Daniel have found each other, only to be painfully torn apart: Luce dead, Daniel left broken and alone. But perhaps it doesn't need to be that way. Luce is certain that something --- or someone --- in a past life can help her in her present one. So she begins the most important journey of this lifetime, going back eternities to witness firsthand her romances with Daniel and finally unlock the key to making their love last.
