Phoebe has always cared for the captive birds of the royal garden. Her friend, the prince, often visits her there, and together they dream of exploring the world beyond the kingdom. But when the king dies, the prince leaves his uncle in charge, and sets off alone. As keeper of the birds, Phoebe must remain within the garden's high walls.
Three years pass. A prize bird escapes, but another, the rare River Flute, arrives in the land. Phoebe agrees to the uncle's if she captures the River Flute, she'll gain her freedom. If not, she'll be punished.
Phoebe gladly sets out on her search, but the hardest part of her journey is just beginning.
Although the uncle is portrayed as the villain, and is indeed a pretty worthless character, I felt the Prince was nearly as much to blame since he choose to not only ditch all his responsibilities but apparently didn't give a second thought about what would happen to his non-aristocratic friend when he left. What a selfish jerk.
I am making up my own ending for this one. The bird the River Flute is magical and turns Phoebe turns into a bird. She flies off to freedom and becomes the protector of hunted things everywhere.
