Living in the remote town of Tierra del Sol is dangerous—especially in the criatura months, when powerful spirits break free from their home in Devil’s Alley to threaten humankind. But Cecelia Rios has always believed there was more to the criaturas who roamed the desert, much to her family’s disapproval. After all, it’s common knowledge that only brujas—humans who capture and control criaturas—consort with the spirits, and brujeria is a terrible crime.

When her older sister, Juana, is kidnapped by El Sombrerón, a powerful dark criatura, everyone in town believes she’s lost forever. But Cece is determined to bring Juana back. To get into Devil’s Alley, though, she’ll have to become a bruja herself—while hiding her quest from her parents, her town, and the other brujas. Thankfully, the legendary criatura Coyote has a soft spot for humans, and agrees to help her on her journey. With him at her side, Cece sets out to reunite her family—and maybe even change what it means to be a bruja along the way.
