This is volume four in a series. I have not seen the others, but if this is anything like the previous three were, then it's an epic series and an awesome book to give to a child. The only problem with it is that it is not very ethnically diverse.
Each page consists of a large double page image, all of them done in the manner of Maurits Escher. If you're familiar with his work, you will know the kind of thing to expect here, but this is aimed at younger set, and will definitely draw children in so much that they might not wonder why a person with a wonderfully diverse name like Rob Gonsalves doesn't incorporate more of it into his illustrations. Among the author's influences were Dali, Escher, and Magritte. I recommend this for the artwork.
