The Bewitching by Silvia Moreno-Garcia

A chilling multigenerational tale where three women across different eras brush with witchcraft and dark forces. Minerva, a graduate student researching horror author Beatrice Tremblay, discovers that Tremblay's novel was inspired by a real disappearance—and that the same sinister presence may haunt her university today. Echoing her great-grandmother's terrifying 1900s Mexico encounter, Minerva realizes an ancient shadow connects them all. From the New York Times bestselling author of Mexican Gothic comes a spine-tingling saga where academic curiosity becomes dangerously supernatural.
