Who Will Like This Ending
Readers who enjoy endings that are chilling and ironic will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how Richard Matheson closes the story, which is exactly why many readers look it up. Either way, the final chapters reward a second look once you know where everything is heading, because small details from the middle of the book start to matter.

Discussion Questions About the Ending
If you are reading I Am Legend with a book club or a friend, these questions work well once everyone has finished:
- Did the ending surprise you, or had you seen it coming from the first chapters?
- What does the final scene say about isolation, and do you agree with Richard Matheson's view?
- 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?
- Would you describe the ending as chilling and ironic, or would you choose a different word?

- Compare the opening with the close. Look at how the first chapter introduces isolation and how the ending answers it.
- Track each final choice. The table above shows where every main character ends up, so ask which of those outcomes was earned.
- Notice what Richard Matheson leaves unsaid. Gaps in the last pages are often deliberate, and they are where most of the debate about the ending begins.

Questions to Ask Yourself After Finishing
- Was the ending of I Am Legend earned by what came before it, or did it feel sudden?
