Books told in letters and diaries

Books told through letters, journals, logs or files, so the reader pieces the story together from documents. Anne Frank's diary is the most famous real example, Alice Walker's The Color Purple is written as Celie's letters, and Helene Hanff's 84, Charing Cross Road records a friendship carried across the Atlantic by post. Flowers for Algernon unfolds in progress reports, and Illuminae tells a space war in files.
