1 But Mark does not die in the storm, and he has been left behind. 2 The answers are explained with lots of very convincing calculations. 3 Without the character of Mark Watney, this book would only be a scientific look at survival on Mars. 4 This diary style makes the character of Watney very real. 5 I would recommend this book to all audiences. https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_default.swf
