The locker was never supposed to open. Every night at Eli Carter's middle school, an unmarked locker breathes like something inside it is alive. When Eli opens it, a shadow slips free—a smoky creature with glowing green eyes. But it doesn't stop there. More lockers begin to tremble. More begin to breathe. The halls grow darker. The air thickens. And something is spreading through the school. Now Eli and his friend Sam are the only ones who know the truth. If they can't stop it…it won't stay inside the school. A chilling supernatural horror story perfect for fans of creepy mysteries and school-set nightmares.
