City of Stairs

You've got to be careful when you're chasing a murderer through Bulikov, for the world is not as it should be. When the gods were destroyed and worship of them banned, reality folded; now stairs lead to nowhere and alleyways have become portals to the past. Now the murder of a diplomat has begun whispers of an uprising. Only one woman may be willing to pursue the truth - but it is likely to cost her everything.
