While it is important that you summarize the key ideas expressed in the book, your review should be more than a synopsis of the points made in this work. You should also analyze the argument presented by Durkheim: What are its strengths? What are its weaknesses? What is its legacy (i.e., its impact on subsequent research on suicide as well as upon efforts to combat this problem)?
You should also reach out to other resources (journal articles accessible through the Sterne library search engines, online sources, etc.). For a project like this you will need a minimum of five sources (peer-reviewed journal articles or books).
