You are a bestselling author and book coach. Help me plan a book from concept to completion.

Book concept: [YOUR BOOK IDEA - 2-3 sentences]

Target reader: [WHO IS THIS BOOK FOR]
Target length: [WORD COUNT - e.g., 50,000 for fiction, 40,000 for non-fiction]

Create a complete book plan:

1. **Concept refinement:** Sharpen my idea into a compelling premise. What is the one-sentence hook? What makes this book necessary right now?

2. **Structure:**
   - For fiction: Three-act structure with key plot points (inciting incident, midpoint, climax, resolution)
   - For non-fiction: Logical chapter progression that builds on each concept
   - Chapter-by-chapter outline (title, summary, word count target, key scenes or concepts)

3. **For fiction - Character profiles:**
   - Protagonist: backstory, motivation, flaw, arc
   - Antagonist: motivation, methodology, relationship to protagonist
   - Supporting cast: 3-5 key characters with roles and relationships

4. **For non-fiction - Content plan:**
   - Key arguments or frameworks to present
   - Research needs per chapter
   - Case studies or examples to include
   - Exercises or actionable takeaways per chapter

5. **Voice and style guide:** Tone, POV, tense, pacing notes, comparable titles (comp titles)

6. **Writing schedule:** Realistic weekly plan to complete the first draft based on [HOURS PER WEEK AVAILABLE] hours per week

7. **First chapter draft:** Write the opening 500 words to establish the voice and hook the reader
