The discovery of violet gold, a vital fuel for steam-powered machines, propelled the empire of Great Liang into an age of prosperity. But for Chang Geng, a young man raised on the impoverished northern border, the concerns of the empire are as distant as the stars above. When raiders from the north attack Chang Geng's small village, he discovers that the life he knows is a lie. His mother, his teacher, and even his godfather whom he trusted more than any other, Shen Shiliu, are not what they seem. As enemy nations close in, Chang Geng follows his godfather to the heart of the imperial capital, where a greater fate lies in store for him.

Four years ago, Chang Geng and Gu Yun parted in anger. When fate draws them together again, Chang Geng, a once-awkward teen, is now an elegant and adroit young man. But storms lie ahead. As Great Liang faces foreign pressure from without, Gu Yun finds himself embroiled in turmoil within the imperial court. Meanwhile, as the curse in Chang Geng's blood grows, his feelings for his godfather become more painful to subdue by the day. How much longer can he keep Gu Yun from learning his secret...and what will happen when he can hide it no more?

With the Westerners and their allies pressing in on all sides, the empire of Great Liang enters its darkest hour. Under these desperate conditions, Gu Yun leads the beleaguered Black Iron Battalion to hold the borders. Meanwhile, Chang Geng makes his move in the imperial court, sweeping corrupt officials aside in an effort to stabilize the nation before it's too late. As the two struggle to hold the tattered pieces of the empire together, Gu Yun uncovers a shocking truth about the curse slowly tightening its grip on Chang Geng's mind. But are the deepest secrets of Cheng Geng's past enough to move even the iron heart of the nation's most fearsome general?

As Chang Geng continues his dangerous mission investigating corruption in the south, Gu Yun races back to the capital in hopes of stopping a bloody insurrection. But internal unrest is not all that threatens the throne of Great Liang as foreign enemies gather on both land and sea. When Great Liang's northern foe sends an envoy of peace to the capital, an end to the war may be in sight. But the northern tribes come with their own desperate plan: a mechanism to ignite the curse lurking in Chang Geng's blood and turn him against all he holds dear. To save Chang Geng, Gu Yun must find the secret to the curse of the wu'ergu--before both of them run out of time.
