The Intergalactic Dating Agency: Starlight Mermen is another massive sub-series from Skye MacKinnon, with sixty-four books. The mermen angle distinguishes these from her Viking and Highlander alien heroes by setting the romances in aquatic environments with water-dwelling alien love interests.
The series includes the latest entries published in 2025, with heroes named Fionn, Cerban, and Rainse joining the roster. Like other Intergalactic Dating Agency sub-series, each book follows a standalone couple, and the shared universe connects them loosely. The ocean setting adds a different atmosphere to the standard alien romance formula.
