He and his master hope that he will be chosen as a Dragoneye an apprentice to one of the twelve energy dragons of good fortune. But Eon has a dangerous secret. He is actually Eona, a sixteen-year-old girl who has been masquerading as a boy for the chance to become a Dragoneye. Females are forbidden to use Dragon Magic; if anyone discovers she has been hiding in plain sight, her death is assured. When Eon's secret threatens to come to light, she and her allies are plunged into grave danger and a deadly struggle for the Imperial throne. Eon must find the strength and inner power to battle those who want to take her magic...and her life.
