The Divine Cities

You've got to be careful when you're chasing a murderer through Bulikov, for the world is not as it should be in that city. When the gods were destroyed and all worship of them banned by the Polis, reality folded; now stairs lead to nowhere, alleyways have become portals to the past, and criminals disappear into thin air. The murder of Dr Efrem Pangyui, the Polis diplomat researching the Continent's past, has begun something, and now whispers of an uprising flutter out from invisible corners.

The city of Voortyashtan was once the home of the goddess of death, war and destruction, but now it's little more than a ruin. General Turyin Mulaghesh is called out of retirement and sent to this hellish place to find a Saypuri secret agent who's gone AWOL in the middle of a mission. But the ghosts of past wars have followed her there, and soon she begins to wonder what happened to the souls in the afterlife when the gods were defeated by her people, the Polis.
