In the city of Luma, magic is strictly forbidden, and anyone caught practicing it is thrown into the dark Vaults forever. But Alex has a secret: a deck of Enchanted cards that come alive at her fingertips, showing glimpses of the future. When her foster sister betrays her, Alex is forced to flee for her life alongside her little brother, Louie. Outside the city walls, things are even more dangerous. Deadly creatures known as Twilight Hauntings, including a giant bird of prey and a murderous Night Wraith, are hunting her. Alex does not believe she is an Enchanter's Child, but her magical cards are the only clue to her true identity. To survive, she must uncover who she really is and find a way to defeat the Hauntings once and for all.
