Diana: Princess of the Amazons (Wonder Woman)

From New York Times bestselling authors Shannon Hale and Dean Hale comes a story about making mistakes, learning the hard way, and growing up to become a hero.
Eleven-year-old Diana has an almost perfect life on the island of Themyscira. But even though she has a loving mother and many "aunties," she is an only child. The only child on the entire island, in fact. Every other person on the island is an adult who's the best in their trade and mighty in body, while Diana is small, sometimes clumsy, and not particularly good at anything. She's not Wonder Woman...yet.
What Diana needs is someone her own age whom to talk to. Taking matters into her own hands, she creates a playmate out of clay. It's all fun and games for a while, until things get out of control and Diana has to decide whether she's made a new friend...or a monster!
