The Lending Library of Tomorrows

Behind the laundromat, where there had always been a plain brick wall, Milo found a little door no taller than he was. He ducked inside. A small clockwork librarian slid a card across the counter. Tiny gears ticked inside her chest. "We lend tomorrows here," she said. "Borrow one good day from your own future and spend it today. Just return it by the deadline on the card."
