The Book of Rules

A Picture Book

Brian Gehrlein; illustrated by Tom Knight

Farrar, Straus and Giroux (BYR)



An interactive picture book with dynamic illustrations, in which readers have to follow the rules or risk a run-in with a monster—with a gentle approach to mindfulness along the way.

Beware! This book has rules. You must follow all the rules. If you break the rules . . . Dennis the monster will eat you. And you don’t want to be Dennis-food—do you?

With a laugh-out-loud, interactive style, The Book of Rules invites you to get your sillies out before it’s time to focus and listen to directions. And you better get started, because Dennis can’t wait to eat—or, um—meet you!

Brian Gehrlein lives in Liberty, Missouri with his wife, Katherine, and their son, Peter. The Book of Rules is his first picture book. Brian does his best to follow the rules and has (so far) avoided being eaten. He hopes this trend continues.

Tom Knight is the illustrator of numerous books for children, including Bone Soup; Good Knight, Bad Knight; and The Big Bed. He lives in England with his wife, Tabby, and their two sons, Archie and Seth.
