4.5 Amazing ! Joker423 | 18/01/2011 | See all Joker423's reviews (2) Positively the best book I have ever read. I am 14 and I bought this book because I am interested in science but I didn't know it was going to be so interesting. It covers every aspect of space you want to know and all ages will love it, Explained in great detail but incredibly easy to understand, a fantastic gift for child or teen and interesting read for adults. If I could I would give it 10 Stars.
