Summarise a Non-Fiction Book Into Actionable Takeaways

You read the book, or most of it, nodded along, and a fortnight later can recall almost none of it. Name the title and this distils it: the central argument in a sentence or two, the handful of ideas worth keeping, and how to put them to use. For anyone who reads to change something, not just to finish the book.

**Produce a usable distillation of {BOOK_TITLE}:**
1. The core thesis: what is the book's central argument in one or two sentences
2. The three to five most important ideas, each explained in plain English
3. What the book asks the reader to believe that is not universally accepted
4. The most actionable idea: one concrete change the reader could make this week
5. What the book gets wrong or overreaches: honest assessment of any flaws in the argument

**If you have limited knowledge of this book:**
State that clearly and work only from what you know with confidence.
