In an underwater cave at Kynance Cove lives a mighty dragon. Unbeknown to the many visitors who play on the sand and in the sea throughout the year there. Usually Dragon is happy and content but when the rubbish from all the humans is so carelessly left behind and starts to take over her home she loses her temper spectacularly.  It’s going to take a school of Sea Piskie apprentices to sort this out…and maybe a human or two to help!
