I don’t have reliable details on *Nineteen Quiet Rooms* by Ottilie Marsh in my training data, and I definitely don’t want to make up a twist and have you repeat wrong info at book club tomorrow.

**Quick ways to catch the ending/spoiler tonight:**
- **Goodreads / StoryGraph** – Search the title and check the “spoilers” section or recent reviews; people often discuss the twist in reviews marked with spoiler tags.
- **Wikipedia / SparkNotes-style summaries** – If the book is popular enough, there might be a plot summary page.
- **Reddit (r/books or r/WhatToRead)** – Someone may have asked about the ending.
- **Audiobook sample / preview on Amazon/Google Books** – You can sometimes jump to the last chapters in the preview.

**Book club survival tips if you still don’t finish:**
- Ask open-ended questions like “How did everyone feel about the atmosphere/theme of silence/isolation?” or “What did you think the rooms symbolized?”
- Compliment other people’s interpretations, then say, “I was still processing the ending—what did you all think of the twist?”
- Most clubs are forgiving; you’ll learn the twist from the discussion.

If you tell me the basic setup (main character, premise, genre), I can help you prep talking points and themes so you can participate even without finishing. Good luck tomorrow! 📚

*(Quick check: did you mean *Nineteen Steps* by Millie Bobby Brown? If the title/author is slightly different, tell me and I can try to help with the right one.)*
