In a city where angels congregate in sacred underground conclaves and hordes of demons stalk treacherous streets, three sisters are about to realize that growing wings also means painting a target on their backs.
 
Seventeen-year-old Orr, Mika, and Gabby are on the run. After a demon attack nearly claimed their lives, the triplets’ world is turned upside down when they discover the truth their mother has hidden from them all their lives – they are the reincarnations of celestial beings, fated to fight demons in an age-old war against the forces of darkness.
Archangels.
 
Overnight, Orr, Mika, and Gabby are thrust into a world where strange new powers unfurl like wings, when their mother is taken by the very demons who hunt them for their divine gifts. 
Under the protection of the Khan—a secret institute dedicated to training angels—the three Archangel sisters must learn to harness their new and frightening powers. But even the angelic Khan is not as innocent as it may seem. Dark powers arise, and terrible tests are taken as the sisters confront both angels and demons on their path to a dangerous discovery that will shift the balance between light and darkness. 
 
Like what really happened to their fourth sister.
