Not even finished and I want to review this novel. Brilliant! 5 stars, 10 stars. Whatever the best score you can give it do so. Captivating from the first line. I'm all over a clever story like this where you are fully into the characters and know you are in the best hands. Andy Weir you are well worth waiting for. You take a serious storyline and add an abundance or character, compassion and humour. Thanks for being so entertaining!
