Hidden somewhere beyond the highest clouds is the Castle of Destiny, a school for very special students. They are the Melowies, young Pegasuses born with a symbol on their wings and a hidden magical power. But the castle is also a place where friendships are born, where the Melowies find their courage, and where they learn who they are meant to be. The time has come for Cleo, Cora, Maya, Selena, and Electra to face their destinies.
