Fish out of Water by Mary Janice Davidson.
*be aware adult themed content in this book*
In this the third installment in Fred's story, she has decided to date Artur, Prince of the Black sea. The existence of the mer-folk is no longer secret so someone is needed to keep them from floundering around on the media circuit spotlight. Fred has all the right skills for this job, however she has a difficult time ahead as her real mer-father turns up wanting to overthrow price Artur.
Again I really did enjoy this whole series of books, they had, comedy, humour, romance, suspense and much more. A real lighthearted type of read with a happy ending!
