- Which character made the most important choice in the last part of the book, and was it the right one?
- How would the story feel if it had ended one chapter earlier or one chapter later?
- Does the ending leave you hopeful about the characters, or do you worry about what comes next?

- Track each final choice. The table above shows where every main character ends up, so ask which of those outcomes was earned.
- Notice what Stephen King leaves unsaid. Gaps in the last pages are often deliberate, and they are where most of the debate about the ending begins.
