You happen to be visiting London this summer (or heck maybe you live there), there’s a chance you’ll find books left on the seat of some bus or subway for you. Books on the Underground is a really simple idea: leave a book you love for a stranger to find and ask them to release it back into the world when they are done with it.
A simple sticker on the cover explains the idea to the book’s finder–and karma does the rest.
Pretty lovely idea, no?
