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.

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. less

As Fred the Mermaid tries to fit in with her own kind, she finds herself hooked on both Artur, the High Prince of the undersea realm, and Thomas, a hunky marine biologist. She's also caught between two factions of merfolk: those happy with swimming under the radar-and those who want to bring their existence to the surface.

Fred the Mermaid has taken the bait and chosen to date Artur, Prince of the Black Sea, over human marine biologist Thomas. And just in time. The existence of the Undersea Folk is no longer a secret, and someone needs to keep them from floundering in the media spotlight. Fred has all the right skills for that job, but has a hard time when her real father surfaces and tries to overthrow Artur’s regime.
