Recently, I compared a query letter to a job interview. However, that is only partially correct. If a query letter is you, showing up a little early, dressed in a clean, pressed suit, then your synopsis is what you choose to talk about during the actual interview.
Once you’re past the first impressions (and we’ll assume you wrote a killer query letter), your synopsis is the final chance to hook your agent, get her excited about your project, and make her remember your name above the hundreds of other writers vying for her attention.
What makes a synopsis so daunting? When a writer has the stamina to finish a full-length novel, why does she struggle at synopsis-writing time?
