Catastrophe looms in North Goethalsburg! When twelve-year-old J.D. is tricked into taking possession of a book of spells, his best friend turns their teacher into a zombie. The zombification of Mr. Katz creates general chaos and a not-so-terrific time for near-genius J.D. Teamed with his best friend Rodney, twin troublemakers, and an obnoxious ghost, J.D. must figure out how to change Mr. Katz back from one of the undead before he: 1. Escapes the janitor's closet; 2. Eats their brains; and 3. Wears J.D.'s spleen as a hat. Can four boys armed with a slingshot, two boxes of jelly donuts, and a handy zombie guide battle their mindless teacher and live to tell? Probably not. You'll have to read to find out.
