One morning, Rebecca Holloway finds an old key on her doorstep, with no explanation and no sender. Engraved on it is a single number: 19. When she finally finds the door it fits, she discovers that it only exists between 2:00 and 2:13 in the morning - thirteen minutes that repeat every night, like a wound that never fully heals. Alongside Cole Donovan and Nathan Graves, Rebecca begins to understand that every visit to the room takes something from her and leaves something else in its place. The closer 2:13 comes, the clearer it becomes that the three of them didn't find the room by accident - the room chose them.
