I recommend this book for: grades 2-4
Check out the amazing cover illustration, and you've seen the best part of this book. The concept is an intriguing one - 3 children walk through a magic door in a toy shop into another world, where the moon is a ship and you can buy clouds. The execution, however, leaves something to be desired. For example, the giant who steals the moon is described as always talking like a pirate, yet his actual dialogue doesn't have so much as a "yo ho" in it. The level is difficult to determine as well, as it has some long passages and scientific concepts that seem a bit advanced for a first chapter book. But the illustrations - gorgeous.
