If your school has a bunch of copies of The Joy Luck Club by Amy Tan that nobody has used in years, here's your chance to give it a shot. The story is set up well to break into sections for student presentations. I just took it to the max with full-hour presentations.
Keep in mind these were big groups with a lot of tasks. The general outline would work with a lot of books. I used something similar with Huck Finn. Be sure to remind students to vary their presentation because a full hour of sitting around reading this book is a little boring. This assignment was meant to be open-ended, but it includes a nice rating scale and several areas for potential elaboration.
