In this Asian-inspired fantasy world, political power belongs to the emperor, but also to the Dragoneyes: men who harness the power of the 12 energy dragons named for animals from the Chinese zodiac. Each year, a new one comes to power, and the dragon itself chooses a new apprentice from a pool of 12-year-old boys. Physically lame Eon is thought least likely to be chosen and also has a secret: Eon is truly Eona, a 16-year-old girl. At the ceremony, the Rat Dragon chooses fellow trainee Dillon for the role of apprentice. Eon thinks that all is lost until she sees a dragon no one has seen in 400 years: the Dragon Dragon—also known as the Mirror Dragon. The Mirror Dragon chooses Eon as an apprentice, and because there is no current Mirror Dragoneye, she must serve on the Dragoneye Council herself. She is thus plunged into the dangerous world of the court, which is sharply divided between the emperor and ruthless Lord Ido, the powerful Rat Dragoneye. Fans of Tamora Pierce will appreciate both the strong female protagonist and the cast of shrewd misfits who support her. Although the pace is initially slow, patient readers will be rewarded with high-stakes action in a well-crafted fantasy universe. A second volume will follow, but this one has an ending satisfying enough that readers will not feel cheated.—Megan Honig, New York Public Library
