#Mermaid #IslandLiving #KelseyNotSoBerry #MermaidFamily #Family Meet Finn and Sirena Marin: a brother and sister; and Sirena's two children, Cora and Cody. After the untimely death of Sirena's husband, Finn moved in with his sister to help her raise her kids. Even though she thinks he's a bit of a no-good, do-nothing, Cora and Cody adore him. The Marins all have a secret though. They're all merfolk. Can they keep their secret from friends and neighbors?
