In a near-future world, seraphs and demons fight a never-ending battle. But a new species of mage has arisen. Thorn St. Croix is no ordinary “neomage.” Nearly driven insane by her powers, she has escaped the confines of the Enclaves and now lives among humans. When her ex-husband is kidnapped, Thorn must risk revealing her true identity to save him.
