For the sake of clarity, I am going to state what each star rating means when I review books.
5 Stars

These are for books that I loved and would 100% read again in the future.
4 Stars

These are for books that I enjoyed and would re-read as part of a series or if I was in a particular mood for the book, but this is less likely. These books are overall good, but there were a few things that I disliked.
3 Stars

These are for books that I enjoyed but would probably never re-read.
2 Stars

These are for books that I did not like due to genre and/or plot devices that I do not like, but think that there are others out there who may like this book if they enjoy that type of thing.
1 Star

These are for books that I would not recommend to anyone and thoroughly disliked.
