Shovel thinks Ruler is a know-it-all who can’t loosen up. Ruler thinks Shovel is all play and no work. One sunny seaside afternoon, their two gangs challenge one another to a sandcastle-building contest, and the competition gets heated. Who will build the best castle? Who will have more fun? And when a big wave threatens to ruin their constructions, can they step up to help each other-and maybe cement a newfound appreciation for one another?

This dynamic story from author-illustrator Mike Ciccotello is a fresh take on the end-of-summer blues.
