The importance of your novel’s first chapter cannot be underestimated. It’s the chapter that introduces your book to the world – the chapter that needs to draw in agents and publishers and readers alike. (No pressure or anything!) Unfortunately, there’s no predetermined formula for a perfect first chapter. Every story is different, and so is every opening chapter.

Virtually nobody is able to knock out a flawless first chapter on their first draft.
