A brilliantly imaginative talent makes her exciting debut with this epic historical military fantasy, inspired by the bloody history of China’s 20th century and filled with treachery and magic, in the tradition of Ken Liu’s Grace of Kings and N. K. Jemisin’s Inheritance Trilogy.

When Rin aced the Keju - the Empire-wide test to find the most talented youth to learn at the Academies - it was a shock to everyone: to the test officials, who couldn’t believe a war orphan from Rooster Province could pass without cheating; to Rin’s guardians, who believed they’d finally be able to marry her off and further their criminal enterprise; and to Rin herself, who realized she was finally free of the servitude and despair that had made up her daily existence. That she got into Sinegard - the most elite military school in Nikan - was even more surprising.

But surprises aren’t always good.

Because being a dark-skinned peasant girl from the South is not an easy thing at Sinegard. Targeted from the outset by rival classmates for her color, poverty, and gender, Rin discovers she possesses a lethal, unearthly power - an aptitude for the nearly-mythical art of shamanism. Exploring the depths of her gift with the help of a seemingly insane teacher and psychoactive substances, Rin learns that gods long thought dead are very much alive - and that mastering control over those powers could mean more than just surviving school.

For while the Nikara Empire is at peace, the Federation of Mugen still lurks across a narrow sea. The militarily advanced Federation occupied Nikan for decades after the First Poppy War, and only barely lost the continent in the Second. And while most of the people are complacent to go about their lives, a few are aware that a Third Poppy War is just a spark away....

Rin’s shamanic powers may be the only way to save her people. But as she finds out more about the god that has chosen her, the vengeful Phoenix, she fears that winning the war may cost her humanity...and that it may already be too late.

R.F. Kuang studies modern Chinese history. She has a BA from Georgetown University and is currently a graduate student in the United Kingdom on a Marshall Scholarship. The Poppy War is her debut novel.

From audible.com:

Rin’s story continues in this acclaimed sequel to The Poppy War - an epic fantasy combining the history of 20th-century China with a gripping world of gods and monsters.

The war is over.
The war has just begun.

Three times throughout its history, Nikan has fought for its survival in the bloody Poppy Wars. Though the third battle has just ended, shaman and warrior Rin cannot forget the atrocity she committed to save her people. Now she is on the run from her guilt, the opium addiction that holds her like a vice, and the murderous commands of the fiery Phoenix - the vengeful god who has blessed Rin with her fearsome power.

Though she does not want to live, she refuses to die until she avenges the traitorous Empress who betrayed Rin’s homeland to its enemies. Her only hope is to join forces with the powerful Dragon Warlord, who plots to conquer Nikan, unseat the Empress, and create a new republic.

But neither the Empress nor the Dragon Warlord are what they seem. The more Rin witnesses, the more she fears her love for Nikan will force her to use the Phoenix’s deadly power once more.

Because there is nothing Rin won’t sacrifice to save her country...and exact her vengeance.

From audible.com:

The exciting end to The Poppy War trilogy, R. F. Kuang’s acclaimed, award-winning epic fantasy that combines the history of twentieth-century China with a gripping world of gods and monsters, to devastating, enthralling effect.

After saving her nation of Nikan from foreign invaders and battling the evil Empress Su Daji in a brutal civil war, Fang Runin was betrayed by allies and left for dead.

Despite her losses, Rin hasn’t given up on those for whom she has sacrificed so much—the people of the southern provinces and especially Tikany, the village that is her home. Returning to her roots, Rin meets difficult challenges—and unexpected opportunities. While her new allies in the Southern Coalition leadership are sly and untrustworthy, Rin quickly realizes that the real power in Nikan lies with the millions of common people who thirst for vengeance and revere her as a goddess of salvation.

Backed by the masses and her Southern Army, Rin will use every weapon to defeat the Dragon Republic, the colonizing Hesperians, and all who threaten the shamanic arts and their practitioners. As her power and influence grows, though, will she be strong enough to resist the Phoenix’s intoxicating voice urging her to burn the world and everything in it?
