SEVENTH

Niko Terrell wakes on a freezing metal floor with no name, no past, and a scrap of paper sewn into his jacket: one word, SEVENTH, and six digits. Around him sprawls the Structure, a labyrinth that rearranges itself every twelve hours and kills the careless. Twenty-three young survivors have learned to endure it. Niko thinks he can solve it. But something inside the walls is counting down, and the corridors are learning how they move.
