The Chronicles of Harriet Tubman: Freedonia (2015)

Set in Freedonia - author Milton Davis' world, brought to life in the "Steamfunk!" anthology and fully realized in the Steamfunk novel, "From Here to Timbuktu" - Harriet Tubman and her friend and rival, "Stagecoach" Mary Fields, chase agents of the vengeful Alchemist out of their world and into another, in which Frederick Douglass and a quite different Harriet Tubman govern a country of former enslaved Africans that rivals - and often bests - the United States, England and France in power and technology. Harriet must fight to stop a powerful alliance of British and American soldiers and the elite and fearsome Hwarang warriors of Joseon ("Korea") from invading Freedonia. But a wicked force from Harriet's world has come to destroy Freedonia and all it stands for. Will Harriet and her allies be able to stand against it?
