The Cardboard Kingdom (2018) - Knopf/Random House

Welcome to a neighborhood of kids who transform ordinary boxes into colorful costumes, and their ordinary block into cardboard kingdom. This is the summer when sixteen kids encounter knights and rogues, robots and monsters–and their own inner demons–on one last quest before school starts again.

In the Cardboard Kingdom, you can be anything you want to be–imagine that!

The Cardboard Kingdom was created, organized, and drawn by Chad Sell. Chad co-wrote the book with Katie and nine other authors: Jay Fuller, David DeMeo, Kris Moore, Molly Muldoon, Vid Alliger, Manuel Betancourt, Michael Cole, Cloud Jacobs, and Barbara Perez Marquez. This massive collaboration has gained critical acclaim as well as a hit in both libraries and schools. The Cardboard Kingdom affirms the power of imagination and play during the most important years of adolescent identity-searching and emotional growth.
