5 I'm friends with the author, so this will be just a silent rating
4 Used to like it, now probably an honest 3, I write a review to inform the author of that
3-1 I dropped it way to early to even properly rant, so no review either
5: I like it.
4: I like it, but I want to seem more honest with my rating.
3: Who even rates a book as a 3?
2: Pretty sure no one rates 2's either.
1: I didn't like it.
