This is a great book with a lot of good stuff I wish I knew by heart.
I rate the book 4 stars. Its really, really good.
She lays out the three act structure as:
Act I: Hook containing HOOK and CONFLICT #1
Act II: Development containing CONFLICT #2 and CONFLICT #3
Act III: Climax containing FAUX RESOLUTION and CLIMAX
The new thing she brought to the table for me was breaking down each of these six PARTS so that each part has its own Hook, Conflict (1-3), Faux Resolution and Climax. This is an over simplification of what she's teaching. I see it as a very useful and powerful tool in developing structure.
