The lawyer hands you the keys to a house you've never seen, left by a relative whose name no one in your family remembers. The estate is real and sizable. The condition is simple, handwritten at the end of the will: thirty nights spent in the manor, without interruption. If you leave early, everything reverts to the state. The first night seems like just an old house. By the third, you discover a room that doesn't appear on the building plans. On the seventh, someone from the village stops you in the street and asks if you've already found the journals. Each night spent there reveals something—about the house, about your family, about why you were chosen. Will you stay thirty nights?
