The book review format includes an introduction, body, and conclusion.
Begin with a summary of the book. This is probably a good way to introduce any review because it gives context on what you are talking about. Describe the book cover and title.
Pick out the most important characteristic of the book. Include small quotes as examples. Include any subtitles at this stage.
Find similar books and compare but come out with your own opinion. Give it a star rating if you want. Include the Author's Name.
