"The City of Ravens.

For the first time, Jack Ravenwild's designs exceed his talents. His ambitions plunge him into the middle of a plot to destroy the city, a noble quest to find a lost hoard, and a conspiracy to seize the reins of power through the nobility's Game of Masks. Worse yet, Jack must choose between a life of freedom and saving the city he doesn't even know he loves."
