Cogrind

Jack is a mechanical prodigy. His passion lies among the pipes and catwalks of The Conservatory, the heart and power plant of Cogrind, A machine city, where every street, shop, and plaza can shift and move to the citizens' whim. Marvelous tinkerings and inventions are imagined and forged daily, and all citizens live, work, eat, and sleep as one. Apprenticed under a living legend, Jack is destined to become the next Master Tuner, the man who makes the whole city run on time, until something that shouldn't exist almost kills him.

Sallah is a vicious huntress among the ever-sprawling forest of The Greensea. Born into the House of Hawthorne as a Druida, a leader among the Twelve Houses of Dara, and shaman that can bow Nature to her will. The Twelve Houses are a cutthroat society where the Houses vie for supremacy through cunning and strength. With her ascent to leadership, a cruel and sacred rite is enacted that will cost either her own life, or the lives of the two people she cares for most.

Both will uncover fractures of an ancient conflict that seem to link the two disparate societies. Both will make choices that will unknowingly force them together, and if they can survive, both will find there is a far darker conspiracy that connects both Jack and Sallah, as well as their people.
