The Philosophy of Time Travel

"The Philosophy of Time Travel" is Roberta Sparrow’s essay on the guiding principles of time travel - the book at the heart of Donnie Darko.

This site holds the book, chapter by chapter, alongside the film it explains: the 28-day timeline, every character’s role, the ending, and a glossary of Sparrow’s terms.

Beside the text, a reader’s notes. Two ways in: travel through the book yourself, or leave a question in Sparrow’s mailbox.
