The lack of words in some sections made parts of this a bit hard to follow for me, but avid graphic novel readers will find it easy to draw meaning out of the illustrations and not have to bother with words. This also hits a lot of current social issue topics in a way that is accessible for children.
Readers who like graphic novels with a compelling story line, such as Holm's Sunny Side Up, Jamieson's Roller Girl of Yang's Secret Coders will enjoy this romp, and may even be inspired to create their own cardboard kingdom.
This would make a great gift for a graphic novel fan, especially if there are long car trips planned for the summer. I can see this being pored over many times over the summer!
