"Countless dead lie in the miles of catacombs beneath its streets. And in the necroflux generators that draw out the psychic energies from their bones to power the city, thousands more pay for a life there. But even a city built on death, a city of living gargoyles, a city haunted by wraiths, has people who make a living from crime. Lieutenant Donal Riordan is a good cop. Good enough to find himself picked out for a job protecting a visiting Opera Diva. Not good enough to keep her alive. And now the bones are speaking to Donal. They know him now. He can feel them. He can taste their song. Donal needs to find out who wanted the Diva dead. More importantly he needs to find out who wants him dead."--Jacket
