La Misericordia Orphanage, Zabalburu (Bilbao), 1974. On her sixteenth birthday, Natalia, a young woman who has known nothing but beatings and silence, receives a visit from a rough and cold man who claims to be her father. He has returned. The nuns at the hospice tell her that she will be going to live with him immediately, and Natalia, always obedient, moves to a village house in Santurce, whose walls harbor too many secrets and horrors. She is hungry. Through her dead mother's diaries, the young woman will discover that ghosts can be real, that something has been stalking and haunting her family for generations—for there are inheritances more dangerous than disease—and that something is now looming over her. It is looking for her. To survive, she will have to learn that there are names that must not be spoken, that there are windows and doors that must not be opened, because once that happens, there is no turning back. Don't look her in the eyes. Don't Open the Window is a psychological thriller with supernatural overtones, a heartbreaking story of broken love, inherited wounds, and horrors that know no death. With sharp, immersive prose, Eba Martín Muñoz draws you into a pulse-racing, soul-shaking read. If your window appears open, run!
