Life is trouble-free on Mako Island - until the day that Ondina meets Weilan, a new mermaid from the Eastern pod. They immediately clash and Mimmi has to act as peacemaker. But a far greater threat to the peace of Mako looms, in the form of a fearsome Chinese water dragon that once destroyed the Eastern pod and killed Zac and Mimmi’s mother, Nerissa. Weilan and Zac team up to fight the dragon.
