Synopsis
Human kindergarten teacher Emma unexpectedly finds herself in an underwater merfolk kingdom, where she discovers she can understand merbabies. Using her gift and experience with children, she helps Mermaid King Adrian care for his young niece Lia, saves Red Clan heir Ruby from a deadly plot, and comforts the misunderstood Dark Sea prince. As merbabies from all five clans gather around her, Emma teaches them to control their powers and trust one another, eventually helping them awaken the Tidal Heart together. The five clans finally sign a permanent pact to protect their children, while Emma finds love with Adrian—and a true home beneath the sea.
