“The books that the world calls immoral are books that show the world its own shame.”
Just a quick note on how I rate. I use the standard 5 star system.
5 stars are reserved for the books that had the most impact on me. It can be hard to pull emotion out of me, so if a book can make me laugh out loud or cry, it's a good sign that it's on the way to 5 stars. If I reach the last page, and immediately want to flip back to page 1, that's another good sign.
4 stars are for books that I really enjoyed.
3 stars are for books that I liked. Some borderline-meh books are here too.
2 stars are for books I didn't like, and also some borderline-meh.
1 star is for books I truly felt I would be better off never having read.
I have a 100 page rule. I'll give a book 100 pages to pull me in. If it's not working for me in the first 100 pages, I feel fine in abandoning it. I have a shelf for abandoned books, but I typically won't rate these. Sometimes a book is slow to warm up, or is just the wrong book at the wrong time. If I've got a lot going on in life and I'm looking for an escape, a heavy think piece is just not going to be something I could get into. I will normally revisit my abandoned books and try again, and give proper ratings when I finish.
Also, I tend to not shelf books until I've read them, so the majority of books on my TBR can only be found there.
