Ten years ago, Corinthe made a huge mistake. Since then, she’s been exiled from her sister Fates, living on Earth among the humans. To earn her way back into the good graces of the Unseen Ones and be allowed to return home, she is tasked with helping humans achieve their destinies: whether that means facilitating meet cutes, making someone late for work, preventing an accident, saving a life...or ending one.
