Sarah is just a normal tenth grade girl when something quite odd happens....

The tides are high and the tides are low. The tides connect the sea to the land as they fall on the sand. The world above to the world below. While most only belong to one, very few are lucky to belong to both. Mermaids are thought to be part of fiction, but in a world where Gods are real and aliens frequent earth, they are part of reality. Mermaids are sea dwellers who grow legs once dry, and one mermaid, in particular, may be out of her depth when she comes face to face with an Ancient God of the sea and of the land. The God whose people call him K'uk'ulkan, and whose enemies call him Namor.

Boy meets Fish...

Mermaids, they're not real, well not any more. That's what the crew of the Dark orca thought before hauling one out of the sea, though she's not much of a mermaid. No, she's something much, much worse.

The Cook sisters become mermaids in the sea.
