THE LOCKER IS OPENED. THE NIGHTMARE ESCAPES. Each night in Eli Carter’s middle school, an unmarked locker breathes as if alive. When Eli opens it, he unleashes a smoky creature with glowing green eyes. The creature crawls out, and strange cases known as the Midnight Files begin: lockers that breathe, more lockers beginning to tremble, and finally, multiplying horrors hiding in the shadows. Will Eli and Sam trap the terror before it spreads?
