I had been looking forward to this book after reading a review in a magazine. We are all interested in space in this household, and I have tried to get as many space related books as I happen across. I have seen a few reviews that say they wish they would have known this was a biography that encompassed the entire life of Scott Kelly, but it says right in the title it is a lifetime of discovery, so I am not sure how that was missed? I love biographies in general, and this one was interesting. It was interesting to see how Scott Kelly began his journey to space. I was very interested in the parts of the book that spoke about the effects of being in space on the human body, especially for an extended period of time. Overall, it was a great book, and I am glad I finally sat down to read it.
