I will not hesitate to say that I absolutely loathe science, math, space, and a lot of science fiction books. But holy crap this book is phenomenal!! If Mark Watney, or really Andy Weir, had taught me science or math in school, I have no doubt I would actually have an interest in those subjects. 
 Almost every sentence in this book is a science explanation or math equation, and it just goes to show how great the writing is because I was fascinated the whole way through. Honestly, this was amazing. Watney is a fantastic character and narrator. He's funny, honest, and a brilliant problem solver. I loved being in his head throughout this journey. I was never bored. Not once. 
 So, if you're anything like me and you hate math or science, or even space, please pick this book up and give it a try! I think you will be pleasantly surprised by how much you enjoy it. 
 My only disappointment is that it ended too soon for my liking. And this may be a little spoilery, so if you want to read it without any knowledge of the ending, please jump to the next paragraph. (view spoiler)[ I wanted to see him get back to Earth!! I wanted to know what he was thinking when he finally landed on Earth soil and see everybody. I was so invested in his well being, that it would have done my heart some good to hear more of his happiness of actually making it home! I was sad that it ended when he got to the Hermes . (hide spoiler)] That's literally my only complaint. 
 Overall, this book was exceptionally well written, entertaining, heartbreaking, and joyous all at the same time! I really, really enjoyed it.
