For years, the FBI has quietly dismissed impossible cases as coincidences, hoaxes, or unexplained anomalies. Until now. As reports of strange deaths, impossible disappearances, and seemingly supernatural crimes begin increasing across the country, the BAU is tasked with investigating cases that defy logic. Enter Y/N. Officially, they’re the newest member of the Behavioural Analysis Unit. Unofficially, they’re hiding a secret that could change everything the team thinks they know about the world. Because while everyone else is searching for rational explanations, Y/N already knows the truth. Monsters are real. And some of them are hunting. As dangerous supernatural threats emerge, Y/N must balance helping solve impossible cases, protecting the people they care about, and keeping their own abilities hidden from the team. After all, some secrets are worth dying for.
