"Yigris is a world divided--where aristocrats in Above rule from grand palaces, and thieves, sex workers, and assassins reign in the shadowy tunnels of Under. When the leaders of Above and Under are both murdered on the same night, the fissure between the two opposite worlds grows and suspicion threatens to break the tenuous peace.
