The Third Poppy War is over, but Rin's troubles are only beginning. Haunted by the atrocity she committed to end the conflict, addicted to opium, and tormented by the god whose fire she commands, she wants one thing above all: revenge on the Empress who betrayed their nation. When her plan to assassinate the Empress collapses, Rin throws in with the Dragon Warlord, a charismatic and ruthless leader who dreams of toppling the throne and founding a republic in its place. His campaign draws in the fractious southern warlords and, more dangerously, the Hesperians, a powerful Western people whose missionaries and soldiers have their own designs on the empire. As Rin learns to fight within an army rather than a small band of shamans, she must navigate shifting loyalties, master a power that threatens to consume her, and decide whom she can trust. Set against a world modeled on early Republican China and its warlord era, this middle volume of the Poppy War trilogy is a darker, more politically tangled story of civil war, foreign intervention, and the corrosive cost of vengeance.
