"Four full moons past, humans crossed into the magical lands of Xadia and committed an unspeakable crime: They destroyed the only egg of the Dragon King and Queen. Now a young Moonshadow elf assassin has been sent on her first mission; she will make the humans pay for their heinous act. But before she can complete her task, she and two human princes make an astonishing discovery . . . a discovery that could change everything. And so the three reluctant allies set off in a desperate attempt to stop the coming war. Their journey won't be easy, but the trio soon learns that the most serious threat to their quest can't be fought with magic or physical strength. Can these young heroes overcome the longstanding hatred between humans and elves, and restore peace to their world?"--Page  of cover.
