The Detective Therapy by Chisonari

‎In Emerald Ville, secrets don’t just haunt you. They hunt you. ‎ ‎Gabriella Peters arrived at Guépard Academy seeking the one thing her life in Lloren never allowed: invisibility. Along with her twin, Gabriel, she hoped the elite school’s ancient stone walls would provide a fresh start and a shield for the secret that has already cost her everything. But Guépard is an edifice that eats girls like her for breakfast, and its halls are filled with eyes that see more than they should. ‎ ‎When a sudden, bone-chilling Vision forces Gabriella to save a teacher’s life in front of her entire class, her cover is torched. The "Gift" she views as a curse — a heavy burden of headaches and glowing skin — is now a beacon for a predator. ‎ ‎A vague figure known as the Vandal is playing a lethal game of psychological chess, leaving notes in her locker and Guide that prove they know her mind better than she does and play tricks with her mind by manipulating events that happen in her life. ‎ ‎Alongside the C.L.A.R.G.S.T. — a diverse group of misfits each guarding their own secrets — Gabriella must race to uncover the Vandal's identity. But as the stakes rise and the school’s technology begins to glitch in ways that defy logic, Gabriella realizes the Vandal isn't just toying with the school; they are experimenting on her. ‎ ‎In a place where the walls are always staring, Gabriella must solve the mystery before her Visions stop being warnings and start becoming her tomb. ‎
