A. A. Aguirre - Bronze Gods (Apparatus Infernum 1, epub)[j_ray]

Danger stalks the city of steam and shadows.

Janus Mikani and Celeste Ritsuko work all hours in the Criminal
Investigation Division, keeping citizens safe. He's a charming rogue
with an uncanny sixth sense; she's all logic--and the first female
inspector. Between his instincts and her brains, they collar more
criminals than any other partnership in the CID.

Then they're assigned a potentially volatile case where one misstep
could end their careers. At first, the search for a missing heiress
seems straightforward, but when the girl is found murdered--her body
charred to cinders--Mikani and Ritsuko's modus operandi will be
challenged as never before. Before long, it's clear the bogeyman has
stepped out of nightmares to stalk gaslit streets, and it's up to them
to hunt him down. There's a madman on the loose, weaving blood and magic
in an intricate, lethal ritual that could mean the end of everything...
