In a magic-rampaged Philadelphia, Tess Wright knows that the only thing more dangerous than the monsters in the shadows is the void within.
Twenty years ago, a mysterious plague decimated civilization, bringing with it rampaging elemental forces and mutant beasts. Tess works as a scavenger, hunting through the ruins of the old city in search of relics to sell, keeping herself at a distance from former friends and her own estranged brother. Because Tess has a secret: she is a black hole for magic, capable of siphoning and destroying the very energy that powers the world.
Her solitary existence is shattered when she rescues Bailey, a young girl who radiates an impossible power that defies every known law of nature. Only Tess's magic-erasure can keep Bailey's volatile outbursts in check, a task made more difficult by the ruthless cult that will do anything to reclaim Bailey. But the people chasing after them are only the beginning. A nightmare from Tess's own childhood is returning, putting the entire world at risk. To protect those she loves, Tess must decide if she is willing to become the monster she has always feared.
