Choose a book and begin by researching the author, his life, education, personality and writing style. Often a book is just an extension of the writer. How he came to write the book and his reasons for telling his story say much about the author as a person. Personal elements, traits, quirks and his own opinions might subtly appear throughout his literary works.
Read the book carefully and thoroughly. Highlight or take notes on key elements and meaningful passages. Pay close attention to underlying themes and back stories. You might have to read some portions more than once to fully comprehend the what the author is attempting to relay to the reader.
Decide whether there is a message or a theme, what that message or theme consists of, and whether the author was successful at revealing this effectively to the reader. Remember, writing about literature is your personal opinion of the book. There is no right or wrong. Your feelings about the quality, content and messages make up the body of a literature review, so write your honest evaluation in clear, concise terms.
Review the positives and the negatives of the book. Factors to consider are clarity, pace, plot, length, dialogue, character, style and story structure. Evaluate what the author could have done better to make his literature more appealing and what you believe to be well written and add this to your written review.
Compare the book to other books by the same author. Decide whether the current piece of literature was his best work or if you feel one of his other books exceeded this one and tell your audience why you feel that way. End your review with a short summary and a decision on whether you would read another book by the same author and state your reasons.
