My first impression of the book was -tiny. The book is just under 4" across. My second thought was, it is not really a pop up. Instead it has a cut out circle on each page with one planet on each, except the one facing a brilliant photo of the sun, and one showing an asteroid belt. Although I was a little bit disappointed, the book does have beautiful illustrations, and at least it was cheap enough. At this point my son saw the book so it was some time before I was able to browse any further, but basically that is it. The text is very limited giving some basic stats on each planet such as circumference, atmosphere, core, distance from the sun, length of days and years etc..
My son had no idea he was getting this so he was not expecting a pop up or anything else. Perhaps that led him to appreciate this book more than I initially did. He quickly sat down with it and began looking through the pages, tracing the planets with his fingers and stretching the book out and folding it up ( it stretches out like an accordion). After awhile he wanted it read to him and then sat down exploring it again. The next day I picked it up to read to him and was surprised that he instead pointed out each planet and gave me it's name. He has just come in and told me this is the best space book because he likes the way the pages go together. I think he means the 3-d effect of the planets.
Even my two year old has enjoyed this book, although he certainly does not know what he is looking at, and it is a book both children will seek out and sit down with themselves. It is also well made with thick sturdy card pages. Because of the reaction of my sons to this book, it's reasonable price, and the fact that I am pleased he learned his planets so easily, I have reconsidered my hasty judgement.
I would highly recommend this book now, both to introduce children to teh wonders of space, and just a love of reading. I have given this book 5 stars only because Amazon will not allow me to give it 10. Very highly recommended.
