Epistolary fiction

Epistolary fiction is a story or novel told in the form of a series of letters; or, more broadly, diary entries or other documents. Its popularity during the Victorian era has led to a resurgence of the form in steampunk and other fiction taking place in alternative Victorian times.

SF examples include:

• The Beatrice Letters by Lemony Snicket
• Dracula by Bram Stoker (1897) includes a wide variety of correspondence
• Emma Bull and Steven Brust's Freedom and Necessity (1997) is a recent example of letters, diary entries, and some live action
• Caroline Stevermer and Patricia Wrede collaborated on Sorcery and Cecelia or The Enchanted Chocolate Pot: Being the Correspondence of Two Young Ladies of Quality Regarding Various Magical Scandals in London and the Country (1988); sequel The Grand Tour: Being a Revelation of Matters of High Confidentiality and Greatest Importance, Including Extracts from the Intimate Diary of a Noblewoman and the Sworn Testimony of a Lady of Quality (2004), turns from letters to diary extracts and testimony.
• The Fox Woman by Kij Johnson is a series of diary entries
• The Historian by Elizabeth Kostova (2005) is a partial epistolary novel
