In Sleeping with the fishes, when Fred, a cantankerous mermaid who is neither blonde nor buxom, volunteers at the New England Aquarium, she stumbles upon a mystery involving high levels of toxins in the local seawater that leads her to a sexy marine biologist. In Swimming without a net, while trying to fit in with her own kind, Fred is torn between Artur, the High Prince of the merpeople, and Thomas, a gorgeous marine biologist who has the opportunity to explore where no "lander" has gone before. In Fish out of water, when the existence of the Undersea Folk is exposed to the public and a media feeding frenzy ensues, Fred the mermaid becomes their spokesperson and finds herself thinking about Thomas, the human marine biologist she has left behind.
