1 star - (I didn't like it) This book sucks like a black hole, it's so bad.
2 stars - (meh) I'm never going to get back the hours of my life I spent reading this, am I?
3 stars - (medium quality and enjoyment) I enjoyed this while reading it, but, like Chinese food, it isn't going to stick with me for very long.
4 stars - (good!) This book was intriguing enough that I kept thinking about it after putting it down. I may have re-read a few passages and I may read the whole thing again sometime.
5 stars - (awesomesauce!) I not only couldn't put this book down, I didn't. Once I finished it, I read it again.
