Zuli is extraordinary-she just doesn't realize it yet. Raised by mystical bird spirits in the branches of the Great Tree, she's never ventured beyond this safe haven. Until now. A sinister force threatens the life-giving magic of the tree, and Zuli, along with her guardian owl, Frowly, must get to the root of it. So begins an adventure bigger than anything Zuli could've ever imagined-one that will bring her face-to-face with an ancient dragon, the so-called Witch-Queen, and most surprisingly: her true identity.
