The Possession of Alba Diaz is Haunting Historical Horror

Isabel Cañas’s debut novel, The Hacienda, quickly established her as a potent new voice in the horror genre in 2022, thanks to her grasp of period details, Gothic intrigue, and character. Now, with her third novel, The Possession of Alba Diaz, Cañas is back with another must-read piece of historical horror, drawing readers into a new era of Mexican history, a new supernatural subgenre, and a new story of a woman gripped by dark forces in a world she fights to control.
This time, Cañas takes us back to the Mexican state of Zacataces in the mid18th century, when Spanish colonists were seeking their fortune and plague was sweeping through the area. It’s here that we meet Alba Diaz, the adopted daughter of wealthy Spaniards who’s been pushed into a comfortable but cold betrothal by her family’s business interests. In an effort to escape the spread of disease, Alba, her family, and her future in-laws all decamp to an isolated village built around an old silver mine. It’s here, amid refineries thick with mercury and the strange class tensions between the mine’s wealthy owners and its workers, that something awakens, something old and dark and drawn to Alba. Soon, she finds herself facing everything from scary bouts of sleepwalking to the creepy feeling that something is alive and moving beneath her skin, and only her fiancé’s roguish cousin, Elias, seems to notice.
As with her previous novels, Cañas’s grasp of the Gothic in The Possession of Alba Diaz is both immediate and spellbinding. This is a book about aristocrats crossing an ocean to claw deep into the Earth for wealth, only to awaken something with their greed. It’s a book about arranged marriage and the tension of real attraction versus. manufactured comfort, a book brimming with charged conversations, and a book that knows when to carefully and gracefully introduce the supernatural into what’s already a gripping narrative. A key factor in whether or not a historical horror novel works is whether or not you’d be interested in this world and these characters without the introduction of any horror elements, and through Alba’s point-of-view chapters, it’s clear that Cañas is just as invested in the time, place, and people of mid-1700s Zacatecas as she is with the possession narrative.
