Many times, prologues are nothing more than info dumps, and that can cause readers to skip over them. If you are considering one for you WIP (work in progress), ask yourself the following questions first:
- What is the point?
- Is the information necessary for the reader to understand your book?
- Is this the only way to include that information in the story?
- Is it short? (It should be less than three pages.)
If you keep these questions in mind, you can create (if needed) a prologue that is vital to the story and one your reader will enjoy reading.
