Seriously. This book was amazing. Mark was hilarious and so real. He was brilliant, hard working, and such a positive person in such a terrible situation. The other characters were phenomenal as well. It made me feel all the emotions. It made me scared, nervous, anxious, stressed out, but also happy, hopeful, and it made me laugh. So. Much. The scientific side of this was so interesting. I was never lost or confused when he explained things, but it didn't feel like info dumping. The whole story was fabulous but I will say that the ending was absolutely spectacular. I cried. This book gave me hope in humanity. 

Everyone should read this book. Stunning. It lived up to all its hype. I can't wait to see what else Andy Weir has to offer in his future works.
