To begin, THE BOOK OF RULES was never supposed to happen. It was just a silly book I wrote in 2017 that was never queried and never shared with my agent because I thought it was dead. However, we wanted to find another project to go on submission with so I took a dive into the dusty corners of my Google drive. And there it was. Lifeless and forgotten…THE BOOK OF RULES. Recalling concepts from The Princess Bride, I wondered if it was all dead or just mostly dead. I decided to find out. Through the magic of revision, several amazing critique buddies, and 10,000 volts of figurative electricity, we brought this “dead” story to life. Ta-da! A once thought dead manuscript Frankensteined to a multi-house offer debut book deal. Moral of the story? Keep an open mind and doubt your conclusions—what if your “worst” story is actually your best?!

So far what I’ve observed about the kidlit industry is that it feels like nothing is happening and then everything is happening. And then nothing is happening. And then EVERYTHING IS HAPPENING! Soon art was happening. Soon a monster was happening. Soon Dennis was happening. Yes, Dennis. Because what’s a good name for a monster that eats children who don’t follow the rules? Obviously Dennis.

Throughout the process, Tom Knight confirmed himself to be the kidlit illustration wizard I knew he was. His stuff is amazing and I couldn’t be more pleased to share this book with him! The first time I saw the cover, I remember shouting, “IT’S DENNIS! HE’S PURPLE! MY NAME IS ON A BOOK!” Crazytown. Bonkersville. A rush of blood to the head with two parts sugar and one part imposter syndrome. Because this book was never supposed to happen…and then it was.

THE BOOK OF RULES is a meta, interactive story that playfully introduces the idea of following rules (lest you be eaten) while weaving in a subtle thread of mindfulness. Due to its meta nature, I love that Dennis is eating the book on the cover—a bit of foreshadowing for one of my favorite parts at the end! I also think Tom really captures the playful tone I was going for with the color scheme and design of Dennis. Look how hungry he is! He’s adorably awful. Marvelously monstrous. I can’t wait for him to break out of this cover and munch his way into your hearts…and also eat your children (unless of course, they follow the rules).

From the publisher: 

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!

THE BOOK OF RULES (FSG/BYR) comes out October 19th and is available for preorder.

Brian Gehrlein is the author of dozens of award-winning children’s books that you haven’t read because they don’t exist yet. If only you had a time machine to fact check this absurd claim. Alas, you do not so you’ll just have to take his word for it. Brian enjoys writing snarky pretend-bios at the end of his posts which you can read at pbspotlight.com. Brian thanks you for reading this post. He thanks you for reading this unhelpful non-bio. He especially thanks you for reading this sentence. It was a really good sentence. However, he does not thank you for reading this sentence. You were not supposed to read that one. It was a secret and you’ve gone and compromised the entire mission. What mission you ask? Well, if you even have to ask then you don’t have a high enough security clearance and probably aren’t that cool. For more snark, follow Brian on Twitter @BrianGehrlein.


Tom Knight grew up on Mersea Island on the Essex coast, where he returned to live after having children of his own. Having grown up on a small farm, Tom spent most of his time using his imagination to create new worlds from the hedgerows and haystacks.

After an enjoyable stint as a graphic designer, Tom is now proud to be using his imagination as a full time career. Drawing on a long and abiding love of imagery from childrens literature, Tom has worked for a diverse range of publishers, including Little Tiger Press, Templar, Simon and Schuster, Scholastic and Macmillan. He has also turned his hand to authoring his own titles and is the author and illustrator for the ‘Good Knight, Bad Knight’ books and ‘Jimmy Finnigan’s Wild Wood Band’.

He does all this from a poorly temperature-controlled studio in the garden, where he is constantly distracted by the greedy birds that hang out by the feeder outside his window.
