If you've ever wondered what it would be like to be stranded anywhere by yourself - this is definitely a book you'll want to check out. I don't think I've ever had a book keep me at the edge of my seat while making me feel like I'm learning something. That is exactly what I got with this book. Mark Watney is such a likable character because he is basically that really smart guy in your class. You know the one - he seems to know everything, but is kinda funny and dorky at the same time. I honestly loved his character and wish I could take him out for a beer or two.
