My book review rating system explained:

5 stars — Extraordinary in every aspect from plot, characters, and writing. Never a dull moment. Nothing lacking.

4 stars — An enjoyable book, but missing a few things to make it a 5 star book.

3 stars — An average book. May contain enjoyable elements, but nothing extraordinary.

2 stars — Most likely a book that I marked as DNF, but had some positive aspects.

1 star — I really wish I could say that I haven’t met a book I didn’t like. Reserved for books that I simply can’t like no matter how I try.
