A supportive commentary and 68 in-depth questions which guide the reader to a deeper understanding of the themes, and characters of the text. Even if you know this text well, I think you will gain new insights. I have not seen a more detailed and thorough Study Guide.
The questions are designed to stimulate thought and to open up interpretation, not to test. They are particularly good for group discussion in class e.g. jigsaw groups), but can be used for self-study, homework, formal presentations, written answers, etc.
