City of the Snakes — Darren Shan

For ten years Capac Raimi has ruled the City. Created by the first Cardinal to continue his legacy, Capac cannot be killed.

Then Capac disappears. His trusted lieutenant, Ford Tasso, suspects the mysterious villacs, ancient and powerful Incan priests. To Ford, only one man has the cunning to outwit such adversaries-Al Jeery, who has taken the guise of his father, the terrifying assassin Paucar Wami.

Al has no love for Capac and no wish to tangle with the villacs. Until Ford promises him the one thing he truly craves-retribution against the man who killed those he loved most and destroyed his life. Lured into the twisted, nightmarish world of the Incan priests, Al will learn more about the City than he ever imagined, and be offered more power than he ever desired.

But in the City, everything comes at a cost...
