The audiobook was so great! I've never finished an audiobook as quickly as I finished this book. I found myself looking for excuses to listen to it: doing laundry, an extra walk, etc. Even when I wasn't listening, I was thinking about this book. The technical science and descriptions made me feel like I could actually understand the science and math behind space travel/engineering (yeah right), and the humor was well placed and right on point. Loved it!
