Nia and the new free library

When Littletown Library is destroyed by a tornado, it seems like book-loving Nia is the only one who cares; so she starts the "new free library" under the tree where she used to read, and writes out familiar stories and rhymes that are just a little bit wrong, and encourages the people who check them out to correct them--until soon the whole of Littletown is filled with people reading and writing books.
