Lily loves reading, her head is constantly in a book and everybody calls her 'Library Lily'. Then one day she goes to the park and meets, Milly. Milly doesn't care for reading and would rather explore and find her own adventures. When these two very different girls come together, they each teach the other something important about the excitement a good book can give and the excitement you find in discovering your own adventures-as long as you have your best friend around!
