How it works

Nobody narrates an epistolary story. The reader is handed the papers and works out the rest. Each prompt names the documents and who writes them, and the line under it says what none of the writers puts on the page.

Epistolary story ideas with one voice or several

The line under each prompt counts the voices. Novels in letters are sorted the same way, by how many characters' letters they hold: one, two, or three and more. With one voice the reader hears a single side, as in a cat-sitter's calm daily notes. In a family group chat, five people give each other away.

What the documents leave out

The words after Unsaid are the story. A farmer's diary records nothing but the weather in the week of his daughter's wedding, and rain is only a problem on Saturday. Write so that a reader can work the unsaid part out, and let no writer state it.

  • Date every document. The gaps between the dates are part of the story.
  • Let each writer skip what the person they are writing to already knows.

Questions and answers

What is epistolary writing?

Storytelling through documents. An epistolary novel is told in letters that its characters send one another, and the word reaches English through Latin from the Greek for a letter. The name is often stretched to take in diaries and newspaper cuttings.

Can an epistolary story be told in texts or emails?

Yes. More recent epistolary fiction counts electronic documents such as emails and blog posts. The messages group here uses voicemails, out-of-office replies, a shared document and the tracking updates for a parcel.

What makes a good epistolary story idea?

A reason for the form. A sailor mails a letter home from every port and the letters arrive in the wrong order, so the reader has to rebuild the voyage. Told straight, it would be a plain trip.

Are these prompts for writing a real letter?

No. The writers and the people they write to are all invented, and the true reader is someone looking over their shoulders. For a letter to send to a real person, use the friendly letter prompts.
