This is for when your book is finished but the marketing copy isn't working, or doesn't exist yet. It walks through six diagnostic states, from blank page paralysis to platform mismatch, and gives you interventions for each. The core insight is solid: marketing copy promises an experience, it doesn't summarize a story. You get structured templates for back cover blurbs, Amazon descriptions with HTML formatting, taglines under 10 words, and query pitches. It includes a genre-aware framework that maps elemental genres to the promises your copy needs to make. If you've written novels but freeze up writing the 200-word blurb that actually has to sell the thing, this gives you a system instead of a blank page.
