One century ago the world was changed. In forty terrible days and forty terrible nights the oceans rose to swallow the land. Now only the sea and the island nations remain. Naoto Aequitas knows that he is... different. A scaleless mer, he was raised by his father on the outskirts of an underwater nereid city. He knows the ins and outs of his corner of the ocean and has never met another nereid like him. Charles Denali grew up around boats. Part of the second generation of humans born after the Second Flood, life in one of the smaller island nations isn't easy - especially when your luck is as fickle as Charles's. When they both end up stranded on a mysterious island that's home to a hungry amphibious creature, they must work together to defeat it and find a way home. But being stranded on a deserted island with a monster is the least confusing thing about their new partnership.
