The Hook (a Wandering Koala tale)

What if music could do more than affect your mood? What if a song not only got stuck in your head but in the rest of your body as well? What if music became addictive?

Someone has discovered a new melody that is more addictive than any drug and is selling it on the streets. Teenagers are hooked with one listen. Only the intervention of a silent wanderer can save the town from an invisible snare.
