Monster Zombies are Coming for Johnny (Book 3) [EPUB ebook] 
Zombie Crush

The evil witches are back with their brain-dead monster zombies, ready to feast on all the little brains at Sandy Furlow Middle School. When the Club Zombie Hunters least expect it, Ms. Eisenstein and Hailey surprise attack Johnny and take him to another dimension—a world where there is no hope. A dark, eerie place where brain-eating, eyeball-splashing, depraved monster zombies live and breathe. This time, Johnny is alone with no friends, no teachers, and no parents to help.

Ms. Eisenstein and Hailey want revenge, and they won’t stop until they squeeze every last drop out of Johnny. It’s a zombie crush that will take over the town of Sandy Furlow once and for all.
