Iris Walsh narrowly escaped her pretty, popular twin sister's fate as a teen: kidnapped, trafficked, and long gone before the cops agreed to investigate. With no evidence to go on but a few scattered memories, the case quickly goes cold. Now an adult, Iris wants one thing - proof. And if the police still won't help, she'll just have to find it her own way; by interning at the isolated Shoal Island Hospital for the criminally insane, where secrets lurk in the shad- ows and are kept under lock and key. But Iris soon re- alizes that something even more sinister is simmering beneath the surface of the Shoal, and that the patients aren't the only ones being observed.
