I read the novel a few years ago for free. Andy Weir tried to get it published but was knocked back numerous times. So instead released it for free. This is it here,... http://www.misterswift.com/iSTEM/The_Martian_files/The Martian - Andy Weir.pdf Turns out it was very popular and is now being made into a big budget movie directed by Ridley Scott and starring Matt Damon. https://en.wikipedia.org/wiki/The_Martian_(Weir_novel) Can't wait for the movie. This is one for the hard science fiction fan. Anyone who thought '2001 a space odyssey' and '2010 odyssey two' were the greatest movies ever, and movies like star trek are a bit silly, like me, they should like the novel anyway? How the movie turns out I don't know? Hope Andy Weir has made a heap of money from the movie rights. Or perhaps it will depend on how the movie goes? As far as Andy Weir goes, It's all a bit of a nice story of success. See ya's.
