Three women in three different eras encounter danger and witchcraft in this eerie multigenerational horror saga from the New York Times bestselling author of Mexican Gothic.

"In Silvia Moreno-Garcia's sure hands, every uncovered secret is fraught with intrigue and creeping horror."-Tananarive Due, Bram Stoker Award-winning author of The Reformatory

"Back then, when I was a young woman, there were still witches": That was how Nana Alba always began the stories she told her great-granddaughter Minerva-stories that have stayed with Minerva all her life. Perhaps that's why Minerva has become a graduate student focused on the history of horror literature and is researching the life of Beatrice Tremblay, an obscure author of macabre tales.

In the course of assembling her thesis, Minerva uncovers information that reveals that Tremblay's most famous novel, The Vanishing, was inspired by a true story: Decades earlier, during the Great Depression, Tremblay attended the same university where Minerva is now studying and became obsessed with her beautiful and otherworldly roommate, who then disappeared under mysterious circumstances.

As Minerva descends ever deeper into Tremblay's manuscript, she begins to sense that the malign force that stalked Tremblay and the missing girl might still walk the halls of the campus. These disturbing events also echo the stories Nana Alba told about her girlhood in 1900s Mexico, where she had a terrifying encounter with a witch.
