Plan a Twelve Week Serialised Fiction Release Schedule

Chopping a finished novel into weekly instalments without a plan usually means some weeks end mid scene and others drag. This divides the manuscript into twelve instalments that each end on a genuine hook, checks the pacing holds across the run, and gives you a simple promotion line for each week.

**Plan** a twelve week release schedule using this process:
1. Divide the manuscript into twelve instalment sized chunks, each ending on a hook strong enough to bring readers back the following week
2. Sequence the chunks so pacing holds across the full twelve weeks, not just within each individual instalment
3. Flag any chunk that runs too short, too long, or lacks a natural hook at its current cut point
4. Suggest one simple promotion beat per week (a one line recap, a teaser question, or a character quote) that could accompany the release without spoiling what is coming

- A week by week list (Week 1 to Week 12), naming which chapters or scenes fall in each instalment
- One line per week naming the hook it ends on
- A flagged section listing any instalment needing a different cut point
- One promotion beat suggestion per week, kept to a single line each
