Eleven-year-old Diana leads an idyllic life on the island of Themyscira. Cut off from the rest of the world, she's beginning to feel a little alone. Though she has a loving mother and many "aunties," she is an only child. In fact, she's the only child on the entire island! After an escapade goes wrong, Diana gets in trouble for not living up to the Amazonian standard. She just can't seem to measure up no matter what she does. Every other person on the island is an adult proficient in their trade and mighty in body, while she is gangly, sometimes clumsy, and not particularly good at anything. She's not Wonder Woman...yet, anyway. What Diana needs is a friend; someone her own age whom she can talk to. But when she decides to take matters into her own hands, she encounters the unexpected! From New York Times bestselling authors Shannon Hale (Princess Academy) and Dean Hale and artist Victoria Ying comes a heartfelt story about making mistakes, learning the hard way, and growing up to become a hero.
