A haunting mystery thriller set within the halls of a prestigious high school, Glass Castle follows literature teacher Vera Demiray as she begins a new chapter in Ankara-only to find herself drawn into the chilling disappearances of two female students. What begins as an ordinary teaching assignment soon spirals into a psychological labyrinth of secrets, obsession, manipulation, and fear.

As Vera attempts to adapt to her new life, unsettling truths emerge behind the polished image of Karayel High School. Students whisper, teachers avoid certain conversations, and Detective Koray Kaya-a father connected to the school-quietly investigates shadows no one dares to name. When Vera learns that one of the missing girls may have been stalked by a fellow student, she begins uncovering disturbing connections hidden beneath the surface.

Torn between professional boundaries and her conscience, Vera finds herself trapped in a dangerous web where every answer leads to another question. As tensions rise and the mysterious "Glass Castle" reveals itself piece by piece, the line between protector and predator becomes increasingly blurred.

Dark, atmospheric, and emotionally gripping, Glass Castle explores trauma, control, psychological manipulation, and the fragile masks people wear to hide their true selves. Perfect for readers who enjoy slow-burning suspense, layered characters, and psychologically charged mystery thrillers.
