"In The Half-Made World" Felix Gilman takes us on a journey to a different US, a Wild-West that is ruled by different sorts of "demons". There are two main opposing forces called "the Line" and "the Gun". The Line is industrial while the Gun is weaponised. Both forces enslave their human followers - followers who are willing to do anything to enjoy what they see as beneficial changes to their lives.
Both the Line and the Gun have as their purpose to destroy their opponents, paint the West in their image and enslave humans. Servants of the Line are many and found around the industrial sites that flourish. Servants of the Guns are men and woman who want the power that comes with demonic influence.
Both forces discover that a certain "General" is to be found at the House Dolorous, a hospital. They want to find a weapon that this General supposedly knew about. Both send their agents to kidnap the General.
In the meantime Liv Alverhuysen travels west to the hospital. There, she is supposed to help heal the minds of patients. One of these patients turns out to be the General (bet you're surprised now). The parties are bound to meet and fates decided.
I really liked the underlying sense of humor in this novel. "The Half-made World" is well written, and the text flows from one line to the next. I admire that in an author. There is plenty of tension, a good climax and a fitting conclusion
