Adam Bernhard is a young rookie officer on a routine night shift when a call comes in that will define everything that follows. The location is a well-known mental health facility — the same one where his younger sister Allison was recently admitted. Inside its walls, patients are missing. Hospital workers are missing. Somewhere in the history of the Black Rose facility is a connection to the Indigo Children study that no one has been willing to explain. What Adam finds inside is something the building has been containing for a long time, and it is not finished yet.
