Tristopolis Requiem

The cop: Donal Riordan, undead, imprisoned in a coffin below ground. The city: Tristopolis, gothamesque and baroque, its unchanging sky deep purple, its elevators propelled by indentured wraiths, its power produced by necroflux reactors, fuelled by the bones of the dead.

When powerful conspiracies threaten Tristopolis from the far side of the world, can a freed Donal find a way to stop them, and in the process find a reason to carry on existing?
