Cece Rios and the Desert of Souls

Details: 

Living in the remote town of Tierra del Sol is dangerous, especially in the criatura months, when powerful spirits roam the desert and threaten humankind. But Cecelia Rios has always believed there was more to the criaturas, much to her family’s disapproval. After all, only brujas - humans who capture and control criaturas - consort with the spirits, and brujeria is a terrible crime.
