A deadly parasite is infecting the sea creatures and threatening the good folk of Haven Bay in the third volume of Owen's rip-roaring maritime adventure series.
The sea creatures near Haven Bay are acting very strangely, attacking boats, and Alex senses some dark power is controlling them. When he tracks down his friend the water dragon, he finds it's been infected too. If he can't find a way to stop it, the deadly parasite it's carrying could spread throughout the seas.
