The National Book Foundation named its 2026 5 Under 35 honorees - each with a debut book - and lists which past National Book honorees picked them. There's a live ceremony at littlefield in Brooklyn with ticket info and an accessibility contact.
Rules in plain English: one first (and so far only) fiction book in the last five years, plus prize money. Expect readings and a party for early-career novelists/story writers, with a livestream if you're not in NYC.
