Here is my rating system:
5/5 stars: I LOVED this book and now I have to figure out how to fit it on my favorites shelf
4/5 stars: I really enjoyed this book but there were a few things I was not thrilled about
3/5 stars: Kind of fell flat for me but I enjoyed certain aspects of the book
2/5 stars: I didn’t enjoy it but something kept my attention
1/5 stars: Hated it.
DNF: I did not finish this book. I put it down and have no desire to pick it up again. (I have only ever DNF’ed one book so the likelihood that I will not finish a book I am sent is miniscule)
(I also use half stars)
