When eighteen-year-old Rosemary Everheart steps into the long-abandoned Starling Manor, she expects nothing more than cobwebs, shadows, and the creak of floorboards. But what she finds is far more chilling - she isn't alone.
A mysterious boy named Alexander Starling appears, claming to be another wanderer exploring the ruins. With his piercing dark blue eyes and unsettling knowledge of the manor's secrets, Alexander seems almost too perfect, too present. Drawn to his charm, Rosemary agrees to help him uncover the truth about a murder that scarred the house decades ago.
But as she pieces together the fragments of the past - the screames in the halls, the blood on the walls, the locked room at the top of the stairs - Rosemary begins to realize that Alexander isn't what he seems.
Now trapped between the drama and the truth, Rosemary must confront the truth. Will she get out of this alive?
