It isn't the Human Rebellion yet. Someone needs to invent it.

Rynn scrubs floors at the university to eavesdrop on lectures. In a just world, she would be free to attend those classes. But in Korr, humans are the working class: the serfs, the slaves, and the underpaid freemen who keep the gears turning for their kuduk overlords. Not every human is content letting their lives be spent for the kuduks’ ease, and some have started fighting back. Rynn will have to use her stolen technical knowledge, her wits, and all the bravery she and her friends can muster to win the freedom that mankind deserves. She’s seen what mankind is capable of.... In her dreams, she lives another life, in another world where humans control their own destiny. She’s willing to die if that’s what it takes to bring that same freedom to Korr.

Cadmus Errol, the Mad Tinker, is the greatest inventor Tellurak has ever known. Ever since learning of the link between Tellurak and Korr, he has worked to bring about the downfall of the kuduks. Finding and recruiting others who can see both worlds, he has built the foundation of a world-spanning empire. In secret, he has been working under the noses of the kuduk people, slowly laying a trap that will end the war before it begins.  He sold his freedom to gain access to the mechanical wonders of his master’s workshop, and he’ll do whatever it takes to protect his daughter.

But the Mad Tinker has a problem. He trained perhaps a greater inventor than himself. He showed her a world where humans can accomplish anything, and taught her that she can do anything she put her mind to. And now Rynn is looking for payback, and she isn’t waiting to find out what her father’s secret plan might be.
