Wow this book really packed a lot of material into it's 372 pages. There were a few times I thought it must be at least 600 pages because of how much happened in it. It was a good thing though because I wasn't quite ready for it to end.
If you enjoy space exploration you should give it a try. In most books, they only make one trip into space but in this book, we got to experience- four? five? six? I lost count but it was quite a few which was fantastic since those are usually my favorite parts!
