The book report must have an introduction, a body and a conclusion. In the introduction you should provide general information about your book and also mention the topic of your report. Include the title and the author, the year, the publisher and the number of pages, mention the genre and write about one or two sentences of a brief summary to start the report.
The next several paragraphs form the body of the report. Define what you are going to write in each paragraph using the professor's assignment. Express your opinion about this book: whether it is strong and capturing or boring, compare it with other works written by this author or with other books of this genre.
In the second paragraph, go to the heart of the book. Write about the major ideas, themes and motives of this book. Evaluate them: how they influence the reader and do they find emotional response? Decide if this book is worthy of reading.
You do not need to write a summary of each chapter. You need to choose the most significant. Make a general review of author's main points, arguments and try to define the thesis. What conclusions does the author make? Can you agree with his opinion?
The last part of the report is the conclusion. Here you should summarize the report: restate the main idea of your work, express your own opinion about the book. Try to convey your impression about the book to persuade your reader to read the book if you like it.
Before you submit the final copy of the report, read it again and reorganize if something is wrong. Check the format, clarity, logic and grammar. Each paragraph should be connected with the previous one; each sentence should flow into the next one. Look through your assignment and if the report meets each requirement, you can submit it.
