Journey to the Black City — Keith R. Mueller

In this world there is only a tentative peace; there are those in the Black City of the West for whom only one thing matters; the power to dominate and subjugate; the power to kidnap and enslave children & women into a sexual bondage purporting to save their souls, but in reality to supply wealth to a priesthood whose hearts are as black as the zeppelins they fly. Into this steam-power world, two young people must journey. It will be a journey from innocence that will carry them from their tribe into the black heart of the basalt city. It will be a journey that will change them forever; and bring them closer together than they'd thought possible.
