When people say their pain level is a 100 out of 10, I wanna smack them. However, I’m gonna say this is a 100 out of 5 stars. I listened to this on audiobook at least 3 times, the first two times were consecutive. It’s funny, cute, the right amount of scientific, sci fi, not fantasy, great ending. I personally think it’s better than The Martian. Every book I read or listen to in the 1.5yr since this book, I’ve compared to this one. None of them compare, none are as wonderful as this read (or listen).
