The book reminded me a heck of a lot of Douglas Mawson's Home of the Blizzard, which features his survival in Antarctica after a disaster some 500km from their base,
He has a similar improvisational style, manufacturing what is needed to survive, and simply perservering through force of will, despite numerous setbacks.
Many reviews like this one complain that the subject never falls into despair, yet when you read a lot of first hand accounts of survival, very few actually do experience much despair. When they do, they certainly don't write about it - it just isn't something they waste energy on. Mawson has a quote I've never forgotten - upon pausing for a break in the sun one day because his feet hurt, he peels off his boots and socks and the soles of his feet come away with them. He writes Was there ever to be a day without some special disappointment? . He then dried them, bandaged them up, put his socks and boots back on and kept on walking - because there was no other option.
Weir's book is well researched and compelling entertainment. I'm very much looking forward to the movie.
