Your goal is to seduce the literary agent into wanting to read more. Just like you would a regular reader, your copy needs to speak for itself. In this case, it’s the query letter. At a bookstore, this is similar to the back cover or inside flap copy. Consider how you’d summarize your book to a potential reader in just a few sentences—now imagine doing that for an industry professional who’s evaluating whether your book has the commercial appeal, market viability, and sales potential to succeed.
