There's a Zombie in My Bathtub

Summary

Hi there, I'm Hank.
Here’s what you need to know about me: I don’t try to make the kids in my class laugh, but somehow I do. Spelling is my worst subject. (Come to think of it, so are math and reading!) I try hard—I really do. So why does my brain always freeze into a Popsicle?
When Hank and his friends watch a scary movie to get ready for Halloween, the movie is a bit too scary for Hank. Suddenly, he sees zombies every time he closes his eyes! Everyone says zombies aren't real, but soon Hank notices people around him acting like the undead. Will Hank have to save his friends and family from a zombie invasion?
