4.25 stars. This book is just as ridiculous as the title and cover would imply. I mean that as a high compliment - B-movie ridiculousness is my favorite subgenre of both horror books and films. Calvin takes a trip to Hell, which has been turned into a candy-filled, Lisa Frank nightmare. When a bunch of emo, poser unicorns show up intending to take over Hell, hilarity and gore ensue. This book is also really funny, and had several passages I read aloud to family. Highly recommended.
