Loved it!

The Martian
von Andy Weir

What can I say? I am a natural science student so just alone this fact means I had to read it. And than I saw the movie and loved it. And the book is even better. Everything happen in it , expect one thing, can happen. The science is real and not science fiction. Mark Whatney is also such a funny guy. Even in this hopeless situation he stays calm, even funny. 
I can only recommend the book.
Awesome!
