The Widening Gyre (2011)

From the back cover:

Welcome to the 19th Century
...that never was!

It is a world of wonder, of horror, of adventure, of magic, of strange technology and unprecedented cultural revolution. This is the age that nearly was, filled with radium-powered flying machines, clockwork automata, and steam-driven computers. It is an age of dark magic, sinister secrets, and unholy cults. It is a time in which the world teeters on the edge of disaster, where the enlightened scientific mind battled against ancient superstition and ignorance, in which the souls of all mankind hung in the balance.
