A book report is a written description, review, or presentation that summarizes and describes the reader’s thoughts and views on a certain book. You can write book reports on any type of book, including fiction and nonfiction. Writing a book report helps you practice giving your opinion about different aspects of a book, such as an author’s use of description or dialog. A book report can take on many different forms. However, when writing a good book report, there are a few basic elements you need to include, such as plot summaries, character analyses, and theme analyses. You can start your book report by explaining why the book was interesting.
