While this book has some minor flaws: too many technical papers, some dispensable developments, the main twist that one feels come from too far away. And narrative facility which is to tell the hero of the story in a newspaper starts to become boring (as it is very often used these days, and I can not help but to see a narrative ease). But otherwise it's all good. The theme of the solitary hero abandoned on Mars that such will succeed Mc Gyver technical feats foolish to stay alive very well exploited. Just like the tone of the narrative, and sarcastic techie, American. No place in this novel existential introspection, to despair and depression: it is fighting tooth and nail, on Mars, in space or in Houston to keep the smallest spark of hope. One goal: bring home Mark, a Robinson Crusoe way Bruce Willis that I liked It is at a frenzied pace, with an outstanding of madness and a lot of humor that we follow the adventures of Mark Watney, whose misadventures seem to have intended to illustrate Murphy's Law. With this book, Andy Weir returns to the fundamentals of science fiction: the credible scientific forecasting in the near future, space, adventure. This may be the beginning of a revival for the genre, especially considering the great strides ahead in the discovery of planets exos. I really thought the film Gravity reading this book, from which to draw a scenario equally spectacular and much more robust. In the hands of good studio and the right director, it's a pretty sure blockbuster. I was a little disappointed with the end of the book, too steep. Yet there were material to extend a little adventure. But I do not sulk my pleasure: I loved this book! Read in English.
