This book was super sciency but I really enjoyed it! The details of the science/chemistry things that went on in this book might bore some people but hey it is a sci-fi book after all so I just went with it. Lots of ups and downs and plot twists, much more than I exected from one dude being stuck on Mars. And also, Mark Watney's logs were hilarious! He's a really fun character, even though he's like one slip up from dying the entire book :P But yes I loved this and I'm excited to see how they do with the movie next month!
