Imagine having to keep a secret from your family and everyone you knew. A secret so big, if it were to be discovered it would threaten not only your own safety, but the safety of others and the well being and preservation of thousands of sea creatures. Now imagine having to keep that secret whilst struggling with college entrance exams, boy trouble, the people you love, and the other unavoidable problems every teenager seems to encounter one way or another as they continue to grow throughout the years.

​The secret? These girls have fins. And whether they like it or not, they’re in this together.

For reasons they, themselves do not understand, all share the same secret that upon contact with water, their human form soon changes to that of a mermaid. Legs? No way, tails are way better. What these girls don’t know is that despite all they have done to protect their secret, it will be all in vain when a marine research team are due to canvas the very area they have grown to love. Their own underwater world is under threat and they’re going to have to put all of their differences aside to try to stop it.
