Evie needs to prepare for the big show on the brand new Moon Colony in three days. She and her jazz-band family have been preparing for this moment for months. But now, her sax reeds are missing.

All the years of practice, the months and months of auditions just to get here, and it could all be lost, because of a single sax reed.
