Brynn Finley is the only mermaid in class who hasn't been able to learn mer-magic. Without it, she can't be a guardian of the sea with her parents and friends. On her quest for answers, Brynn encounters a loveable sea turtle, a pair of selkie sisters, and Phaedra, the great and terrible sea witch. Soon Brynn is over her head in trouble, and she must learn to ask for help if she's going to follow the merfolk oath to be a protector of the ocean and a guardian of the sea.
