My husband doesn't usually do books, but when this arrived in the post it was a good two hours before anyone could get it out of his hands. The whole family ended up joining in and commenting on each illustration or illusion. On the surface, it just seems like some light-hearted fun, and this book certainly is fun. But in addition to being great fun, this is an incredibly educational book as well.
