The Perfect Waters

Twenty-five years ago, Princess Odessa and her beloved hounds saved the waters from an evil that had them gripped in fear for centuries, and they've been perfect ever since.
Until now. With her three grown children returning to the waters, it's an exciting time for all, but their happiness is short lived when an unknown substance begins to threaten their very existence. With the help of her family, O'Asia must now work to get to the bottom of what's trying to harm them, but can they do it alone, or will they need the help of an all-seeing, all-knowing woman up on land?
