The Marduk Expanse
An alternative steampunk/SF universe where elevators to the moon and moon colonies are a thing.
One terrorist blast changed Master Tobias Zimmer's entire existence, relegating him to being nothing more than just a "Coppies" because of the metal replacing his flesh. As the once future Shogun of moon colony Orion 1, he now idles his time away keeping tabs on the Loyalists while his father and brother broker negotiations with the Earth Consortium.
A confrontation with his childhood enemy, Dr. Thorsten Nordenfelt, sets into motion events that cannot be undone and puts Tobias's sheltered heart at the center of the colony's attempts to free itself from the repressive Earth's rule.
