I don't know of a novel called *Nineteen Quiet Rooms* by Ottilie Marsh, so I can't tell you its ending without risking making something up. It may be very new, self-published, or from a smaller press than I have good information on. Or the title or author name might be slightly different from what I have.

Some ways to get what you need before tomorrow:

- **Check the back cover or publisher's page** for the blurb, which usually won't spoil the ending.
- **Read a spoiler-heavy review or discussion guide.** Goodreads reviews often flag spoilers, and publishers sometimes post reading group guides.
- **Ask your book club organizer or a member who finished it** what the main discussion points will be.
- **Tell me what you've read so far.** I can help you think through the themes, characters, or questions the group will probably raise, without spoiling anything you haven't reached. I can also help you draft questions to ask the group so you can take part even if you haven't finished.

If you paste in a chapter or summary, I can also discuss it with you, though I'd only be working from what you give me.
