A while ago, I finished Infernal Devices by K.W. Jeter.

Jeter is credited with creating the term "steampunk" and this is one of his earlier works that could fit under that umbrella, though Infernal Devices strikes me more akin to urban fantasy, with a world that much resembles ours but with some hidden parts.

The book's protagonist is the son of a brilliant inventor who is drawn into his father's bizarre world. The weirdness develops slowly, with some "Shadow over Innsmouth" touchs, some automatons and different groups trying to either recruit or kill the protagonist. It ends with a world shattering bang.

The book stays more true to its Victorian roots than most modern steampunk does, with a main character that is fully enmeshed in the repressed, but dominating, upper class.

A fun read.
