"Limit your letter to three paragraphs. The first should identify title, genre, and market, and give a concise pitch. Position your project against what's been published in the same vein. This means explaining what sets your work apart and why it is distinct in terms of plot, character, or audience. This does not mean declaring your project the "next" Harry Potter. The second paragraph might explain major plot movements or character arcs. Only the third should focus on your credentials. Mostly discuss the project, not yourself."
