Fortune favours the prepared mind..
Mark Watney is in the worst possible situation; he is stranded, left for dead by his crew mates, on Mars. He is the only human on the entire planet, probably the only living thing. Mark, however, is an engineer, a botanist and a fully trained astronaut. He has the resources the aborted mission left behind which include a habitation dome, food to last six people a month, power and equipment to make breathable air and... six potatoes. What he doesn't have is immediate hope of rescue.
Much of this book is Mark's account; he devises solutions to living in his low pressure, very cold environment using historical technology when the 21st century stuff just won't do. He makes a ramp out of rocks like ancient Egyptians and a working sextant similar to those used by 18th century mariners. Totally admirable! Bear Grylls eat your hat!
