What's that, Jack?

Two pups spend the day pondering a mysterious object in this French import. A large blue sphere falls from the sky and plunks down next to Jack and George while they are sleeping. "What's that, Jack?" asks George. Jack has no idea. They poke and prod it. Suddenly it starts to roll, taking Jack and George along with it. It must be a ball! But then…it rolls off a cliff. The object starts to flatten, and Jack and George each grab a corner. George continues to question: "What is it, Jack?" Perhaps it is a parachute. After falling into a river, Jack and George climb into the blue object. Now it appears to be a raft. There are so many possibilities. Set against a pink sandy landscape, with colorful dotted trees and gumdrop rounded hills, the dark blue object stands out strikingly in the attractive, naïve art. Whatever could it be? Curiosity and wonder abound. Alas, the object disappears the next day as mysteriously as it arrived. The characters never figure out what it was but agree: "It was wonderful!" Naturally inquisitive kids will relate to the duo's perseverance. Some readers may be disheartened by the lack of resolution, but others will find the process of discovery and speculating on what the object was just as fun. (This book was reviewed digitally.)
