Fish Out of Water (Fred the Mermaid, Book 3)

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.
