To give you a better sense (or perhaps a more standardized sense) of what I thought of the book, I am going to start putting a star rating out of 5 at the bottom of reviews.
Chart of what the stars mean:
0.0, 0.5 = Just terrible.
1.0, 1.5 = I didn't like this book.
2.0, 2.5 = It was ok.
3.0, 3.5 = I liked it.
4.0, 4.5 = I really liked it.
5.0 = OMG you have to read this.
