This was an absolutely amazing book by Andy Weir. It is probably the second best book i have read this year (after armada (I will do a post on that next week)). It is in the process of being made into a film by Ridley Scott and will almost definitely be an outstanding film.
It has a fairly simple plot but some rather complicated technology in it (they may scoot over that bit in the film). There is a manned mision to mars but when there is a huge storm the astronauts are all forced to evacuate. When the team Botanist, Marc Watney is hit by a peice of metal, the rest of the team believe that he is dead and have to leave him behind.
When Marc Watney wakes up he is faced with a minimum of four years on mars in a Hab designed to last 31 days. All he has left to do is communicate with NASA and survive long enough to get another manned mission to mars.
I didn’t personly have this problem, but someone that i know did: at the beginning, when it is just Marcs reports and a lot of technical gibberjabber, it gets rather slow, but when you get to about 1/3 of the way through, he makes contact and it gets a bit more interesting.
