The Invisible Girl in Room Thirteen

STEPHEN SIMPSON

Some doors should never be opened. Some ghosts refuse to be forgotten.

When fifteen-year-old Alison Locke arrives at the prestigious Waterfall Secondary Academy, she's determined to disappear into the background. After losing her father and becoming invisible in her own mother's new family, fitting in feels impossible.

Then she's dared to spend one night alone in the abandoned Room Thirteen.

The room has stood empty for fifteen years.

Its last occupant, Lily Martin, walked into the lake behind the school on Valentine's Eve and never came back.

Armed with nothing more than a Ouija board, Alison expects a childish initiation.

Instead, something answers.

As disturbing visions blur the line between dreams and reality, Alison discovers a shocking connection between Lily's tragic death and her own family. When students begin dying in increasingly brutal ways, whispers of a ghost seeking revenge spread through the school—but the greatest danger may not be lurking in the shadows.

It may be inside Alison herself.

As memories fracture, reality twists, and an unseen presence grows stronger, Alison must uncover the truth before she loses the one thing she has left... herself.

The Invisible Girl in Room Thirteen is a chilling young adult psychological horror novel filled with haunted boarding-school secrets, supernatural suspense, shocking twists, and a heartbreaking mystery about love, betrayal, guilt, and the monsters we carry within.

Perfect for readers who enjoy atmospheric horror, ghost stories, psychological thrillers, and dark supernatural mysteries where nothing—and no one—is quite what they seem.
