I liked this book because it was such a different book than I normally read. I had a hard time getting through it because like I said its not something I normally read but some of the information was really cool to read. When I first got this book I thought that I would hate it but to see another side of something that I know nothing about was pretty cool. I never knew that I would know this much about this. My fiance loves everything to do with space so of course she also read this and thought it was one of the best bio books that she has read.
