Earlier this month, actress Emma Watson hid books [3] with handwritten messages in the London Underground and New York City subway stations as part of the community project Books on the Underground. Write a short story that begins with a character hiding a book in an unlikely place, like a bus stop or a graveyard or the hollow of a tree. What book would be hidden and why? Is anyone supposed to find it, and if so, what happens after? Is the discovery the beginning of a mystery?
