Helen and her fabled-beast friends help Rona the selkie in a Storm Singer competition. Rona wins by singing up an incredible storm, but part of the prize is to represent the selkies in a much bigger contest. Rona must compete in three gruelling challenges against a mermaid and a blue loon, and carry an important message between the deep sea powers, which will stop them going to war. She desperately needs the help of Helen and her friends. But a giant jellyfish and a terrifying conger eel are among those who will do anything to stop the message of peace getting through. Fans of Helen's first two adventures will be eagerly awaiting this third thrilling instalment. Set in the north of Scotland, this story introduces yet more fabled beasts inspired by Scottish sea creatures and folklore
