Kinning / Nisi Shawl.

Enhanced descriptions from Syndetics:

Kinning , the sequel to Nisi Shawl's acclaimed debut novel Everfair , continues the stunning alternate history where barkcloth airships soar through the sky, varied peoples build a new society together, and colonies claim their freedom from imperialist tyrants.

The Great War is over. Everfair has found peace within its borders. But our heroes' stories are far from done.

Tink and his sister Bee-Lung are traveling the world via aircanoe, spreading the spores of a mysterious empathy-generating fungus. Through these spores, they seek to build bonds between people and help spread revolutionary sentiments of socialism and equality--the very ideals that led to Everfair's founding.

Meanwhile, Everfair's Princess Mwadi and Prince Ilunga return home from a sojourn in Egypt to vie for their country's rule following the abdication of their father King Mwenda. But their mother, Queen Josina, manipulates them both from behind the scenes, while also pitting Europe's influenza-weakened political powers against one another as these countries fight to regain control of their rebellious colonies.

Will Everfair continue to serve as a symbol of hope, freedom, and equality to anticolonial movements around the world, or will it fall to forces inside and out?
