While most of the world has drowned beneath the sudden rising waters of a climate apocalypse, Dinétah (formerly the Navajo reservation) has been reborn. The gods and heroes of legend walk the land, but so do monsters. Maggie Hoskie is a Dinétah monster hunter, a supernaturally gifted killer. When a small town needs help finding a missing girl, Maggie is their last—and best—hope. But what Maggie uncovers about the monster is much larger and more terrifying than anything she could imagine.
