Sleeping with the Fishes (Fred the Mermaid, Book 1) 1st edition

Fred is not your ordinary mermaid. She's not blonde. She's not buxom. And she's definitely not perky. In fact, Fred can be downright cranky. And it doesn't help matters that her hair is blue.

While volunteering at the New England Aquarium, Fred learns that there are weird levels of toxins in the local seawater. A gorgeous marine biologist wants her help investigating. So does her merperson ruler, the High Prince of the Black Sea. You'd think it would be easy for a mermaid to get to the bottom of things. Think again.
