From award-winning author John Meaney comes a thrilling tale of Tristopolis, a Gotham-like city beneath perpetually dark skies, where the bones of the dead fuel the reactor piles, indentured wraiths power the elevators, and daylight never shines. Tristopolis has faced eldritch dangers before, with resurrected cop-turned-PI Donal Riordan at the forefront of keeping his city safe - but this time it's the ones he loves who face the deepest risk. Will he be in time to save them? Or will the only thing left be revenge? PRAISE FOR JOHN MEANEY "John Meaney has rewired SF. Everything is different now." Stephen Baxter "A spectacular writer."
