The fallen have trespassed into Heaven for the first time in eternity. Prepared for battle, Michaela and her Archangels open Heaven's gates to confront the fallen. Only, Michaela's Archangels-her brothers and sisters in Heaven-betray her. And when the fallen attack the sanctuary in the skies through the gates Michaela inadvertently left open, the holy angels accuse Michaela of planning the invasion. One simple mistake with a thousand consequences. Dragged to Earth by an Archangel turned fallen, Michaela will do anything to return to Heaven and save it. In her fervor, she kills the Archangel-something no angel has ever done before. Wingless, without any hope, Michaela welcomes death when an unlikely human ally, Clark, finds her. With the help of Clark and Gabriel, an innocent Archangel whose friendship deepens into something far more torrid and unexpected on Earth, Michaela must prove the holy angels have their own plan for Heaven, and it is one that may prove to be the End of the Days. It may be too late to save herself, but Michaela is the only one who knows the truth about the holy angels. If she fails, she may never be able to return to Heaven. But even that may be a hopeless dream.
