Suffering from the voices of past Avatars for as long as she could remember, Yangchen has yet to earn the respect of Avatar Sceto, her predecessor. In an era where loyalty is bought rather than earned, she finds it difficult to trust her judgment. When Yangchen travels to Bing-Er in the Earth Kingdom on political business, a chance meeting with an informant named Kavik leads to a team working together. Bing-Er is a city ruled by dishonest merchants who have come to despise the fickle Earth King and his whims. To break free from his influence, the traders have found one solution: a mysterious weapon of mass destruction that grants them power. Yangchen and Kavik try to foil their plan, and their unexpected friendship grows stronger. But for Yangchen to become a powerful Avatar, she must learn to rely first on her own wisdom.
