Alice’s Adventures in Wonderland (1869)
Lewis Carroll
In-fiction date: 5/4
On May 4th — the real Alice Liddell's birthday, encoded into Carroll's text as a private joke — a bored girl dozing on a riverbank follows a white rabbit down a hole and falls into Wonderland: a nonsensical underground realm of talking animals, an existentially unhelpful Caterpillar, and a queen who settles all disputes with 'Off with their heads!'
