Summarise a Non-Fiction Book's Core Argument

You want the spine of the book without reading every chapter, or you've read it and want the argument cleanly laid out. Name the title and author and it summarises the core argument as if to a smart friend: the problem, the thesis, the strongest three pillars of evidence, and the conclusion. Suits anyone deciding whether to read it or wanting to retain what they did.

Summarise the core argument of {BOOK_TITLE} by {AUTHOR_NAME} as if explaining it to a smart friend who hasn't read it. Structure your summary as follows: (1) The Problem: what question or challenge does the author claim to be solving? (2) The Thesis: in one or two sentences, what is the author's central claim? (3) The Evidence: what are the three strongest pillars of evidence or reasoning the author uses? (4) The Implications: what does the author say should change as a result? (5) The Weaknesses: what are the two most significant counterarguments or gaps the book doesn't fully address? Keep the whole summary under 300 words and avoid jargon.
