Ever wondered where balloons go when they float away? Well, normally, they end up getting littered on beaches, deserts, or caught on electrical wire. But this children's book has a different ending for our balloons. Follow Mia into the sustainable world of Balloon City as she explores this new eco-city with her balloon friends. This city may be fictional, but the sustainable lifestyle that these imaginative balloons live will give Mia, (and you, the reader), a real lesson on how to keep your own community green. So welcome, and let us take on a tour of Balloon City!
