A chapter book series about five pegasus friends learning to use their magical powers! The Melowies finally start the Art of Powers class which teaches them to strengthen the power they were born with. Clio, having been left at Destino when she was born, does not know the realm she is from and does not know what her power is. She must take lessons in all of the realms in order to find out which she belongs to. Clio learns she is not the first Melowy to be unsure of her Realm. Hidden in away in a book she finds a page that makes her jump: "Such a power will not appear for many years; not until the arrival of a Melowy whose realm will not be known, who will be found…" The rest of the book is destroyed. Clio sees Eris casts a spell that weakens Kora's powers so that she can surpass her in class. Kora and Clio work together to stop Eris and ruin her plan. Kora receives the highest marks, using her Winter Realm power to create a beautiful ice sculpture of Clio for class.
