This is my first review of a book and is a kind of reaction to the one star commentaries that I saw. For sure I have read The Martian a while back and I can see that this book is similar, but I think a lot of people enjoy it (like I did) because of those similarities. Sure, there are a lot of cliché characters but in the kind of hopefully vision of the future that is lacking right now. The stereotipe of scientists from Russia, China, America and other places that set aside differences to save the world is a much needed hope that if the world is at stake we will all come together. Sure, the book is not all fairies and rainbows, the hero is actually a coward sent against is will to save humanity and in the mean time there is almost a surety that there will be wars and the usual humans in the time of an apocalypse, but the overall tone is optimistic and upbeat and is what a lot of us need sometime. So is a fast and entertaining lecture, that you maybe forget after a while what is about, but you will remember that you felt good reading it.
