For a thousand years, The Old Town has stood as humanity’s last bastion against the maalkonis, malignant black mists that reduced the rest of the world to ash. They are kept at bay by rusty machines on the town’s walls. In order to survive, the dwindling population depends on one another. Since a young age, Justīne has embraced the harsh responsibilities that accompanied her apprenticeship on the last farm in existence. Her younger sister, Anna, is beginning her own apprenticeship as well. Learning engineering was not Anna's first choice, but the town's last mage fell to the maalkonis years prior, leaving nothing behind but confusing books and strange runes. When food runs low during a particularly harsh winter, distrust spreads like a plague, and Justīne is blamed for it. As hunger leads to violence, she and her siblings are forced to flee The Old Town, embarking on a perilous journey into the very mists that had formed their cage. Their fight to survive in the dark develops into a hopeful mystery as they follow the breadcrumbs of a mage’s efforts to save the world. Meanwhile something pursues them through the maalkonis…

What was it like? Living in that house. Maggie Holt is used to such questions. Twenty-five years ago, she and her parents, Ewan and Jess, moved into Baneberry Hall, a rambling Victorian estate in the Vermont woods. They spent three weeks there before fleeing in the dead of night, an ordeal Ewan later recounted in a nonfiction book called House of Horrors. His tale of ghostly happenings and encounters with malevolent spirits became a worldwide phenomenon, rivaling The Amityville Horror in popularity—and skepticism. Today, Maggie is a restorer of old homes and too young to remember any of the events mentioned in her father’s book. But she also doesn’t believe a word of it. Ghosts, after all, don’t exist. When Maggie inherits Baneberry Hall after her father’s death, she returns to renovate the place to prepare it for sale. But her homecoming is anything but warm. People from the past, chronicled in House of Horrors, lurk in the shadows. And locals aren’t thrilled that their small town has been made infamous thanks to Maggie’s father. Even more unnerving is Baneberry Hall itself—a place filled with relics from another era that hint at a history of dark deeds. As Maggie experiences strange occurrences straight out of her father’s book, she starts to believe that what he wrote was more fact than fiction. In the latest thriller from New York Times bestseller Riley Sager, a woman returns to the house made famous by her father’s bestselling horror memoir. Is the place really haunted by evil forces, as her father claimed? Or are there more earthbound—and dangerous—secrets hidden within its walls?
