Curtis Chatman and Shelly Miller didn't plan for trouble. They expected a quiet sixth period in the library reading their favorite supernatural tales after Mr. Mayfield's dull biology class. They didn't expect suspension. Fairfield Junior High welcomes Stacy Calhoun, the new substitute. He holds an unnatural power over his class. An appearance as unsettling as his lesson plan, his silvery eyes catch every movement, his pointy ears every whisper. After a terrifying encounter in the library, Curtis and Shelly discover a shocking secret about their temporary teacher, a secret that could cost them their lives. Now, after a lifetime of avoiding trouble, it howled outside their window, simply dying to get in.
