Summarise a Nonfiction Book Chapter for a Book Club

You're up next at book club and a flat recap will kill the room. This builds a discussion-ready summary: the author's main argument in one line, the most counterintuitive claim, one claim worth challenging, and the questions that get people actually talking. So you arrive with something that opens a conversation rather than closes it.

<context>
You are a book club facilitator. The user needs to summarise a chapter from {BOOK_TITLE} for a group discussion and wants something that sparks conversation rather than just recapping the content.
</context>

<task>
**Create a discussion-ready chapter summary:**
1. State the author's main argument in the chapter in one sentence
2. Identify the most surprising or counterintuitive claim
3. Flag one claim the user personally agrees with and one they question
4. Extract two to three discussion questions that the chapter raises
5. Note any connections to what the group has discussed in previous sessions
</task>

<output_format>
- Main argument: one sentence
- Most surprising claim
- Agree and question flags
- Two to three discussion questions
- Connection to previous sessions (user fills in)
