A terrifying new novel from bestselling #HorrorBookTok sensation Ania Ahlborn—the acclaimed author of the modern classic Brother.

Hailed as a writer of “some of the most promising horror I’ve encountered in years” (Seanan McGuire, author of the Ghost Roads series), Ania Ahlborn delivers a novel that pushes the boundaries of horror into a new realm.

Isla Hansen, a mother reeling from a devastating loss, is beside herself when a mysteriously orphaned child appears on the outskirts of the Hansens’ secluded Colorado property. Although strange and unexplainable, the child’s presence breathes new life into Isla. But as the child settles in, Isla’s husband, Luke, and their five children notice peculiarities that hint at something far beyond the ordinary—anomalies that challenge the very fabric of reality itself. The tension within the Hansen household grows, and with it, the sense that there is something very wrong with the new kid in the house.

The Unseen is a haunting tale that walks the line between the familiar and the unknown, drawing us into a chilling narrative where reality itself feels just out of reach.
