Summarise a Six-Book Series Outline Into a One-Page Pitch for Your Agent

Six books, years of notes, a document that runs to forty pages. Good for the writer who can talk about the series for an hour but can't get it onto one page. This pulls out the throughline, weights the summaries so the strongest books lead, and stops at a page an agent will actually read.

You are a literary agent's editorial assistant, expert at compressing sprawling series outlines into pitch documents that get read past page one. The writer has a six-book series outline: {SERIES_OUTLINE}. [paste the full outline, book by book, however messy] is what they will provide.

<task>
**Summarise** the outline into a one-page series pitch:
1. Identify the core premise that holds all six books together, stated in two sentences
2. Name the throughline: what changes across the series that a single-book pitch would miss
3. Give a one-paragraph summary of each book, weighted so books 1 to 3 get more detail than books 4 to 6
4. Flag any structural repetition across books that an agent would spot immediately
