Read the book thoroughly and critically, highlighting anything worth mentioning in the review. For example, any quote or main point that elaborates your opinion about the book should be highlighted.
Begin writing your refer by referring to the main theme, character or place in the story. Use something you observed or something that a reader can relate to to convey that. For example, a review of “To Kill a Mockingbird,” written by Rodman Philbrick starts with, “I've never been to Alabama, but novelist Harper Lee made me feel as if I had been there in the long, hot summer of 1935.”
Assess the target audience and write with their perspective in mind. For example, if the book you are reviewing is for young adults then write the review in a way that attracts young audiences. Any references you give should be relevant to them.
Mention the name and author of the book in the first paragraph of the review and use your creative writing skills in doing so. It should not be bland; make it interesting and creative. Other publications of the author can also be mentioned.
Explain the reasons for your disliking a book in a neutral way, in case someone disagrees with you. Someone else may enjoy a book for the same reasons you didn't like it, and deserves to know that from your review.
Provide the summary of the book after the introductory paragraph. Include a critical opinion with your summary; don't just sum up the plot.
Give some details about the style of writing of the author and the general theme of the book.
Mention the basic background or the context in which the book is written on a priority basis, so that the reader will be able to grasp the purpose or theme of the book. If necessary, you need to research the matter.
