From the bestselling team of Mac Barnett and Matthew Myers comes a hilarious tale of sibling rivalry, moral complexity, and disgruntled monsters, perfect for sharing with your own favorite rule-breakers!

Ian likes rules. His sister, Jenny does not. And when the woodsy vacation house where their family is spending the summer comes with a posted set of rules, it's a certain recipe for disaster: Brush your teeth. Make your bed. And never, EVER, open the red door!

"Barnett focuses his inimitable blend of energy and fiendish imagination on children's fascination with the rules…. No solemn moralizing, just a rib-tickling, slightly subversive read-aloud." —Publishers Weekly

Reader Reviews

Praise

* "Barnett and Myers have created a winning tale of sibling rivalry and, ultimately, loyalty. Barnett's trademark dry humor appears in full force, and Myers' illustrations are wonderfully detailed."
Booklist
* "Readers will (probably) agree that even the most irritating siblings don't deserve to be cooked and eaten. As a rule."
Kirkus Reviews
"Barnett focuses his inimitable blend of energy and fiendish imagination on children's fascination with the rules... No solemn moralizing, just a rib-tickling, slightly subversive read-aloud."
Publishers Weekly
"Painterly illustrations quickly transform frightening images into comical ones, creating a mixture of silliness and creepiness—and alert viewers will notice the red eyes on the stove and rug just before they awaken. A scary but silly sibling story about times when breaking the rules might just be okay. The perfect read to prepare for a stay at a vacation house."
