The year is 1926 in glittering Shanghai: a city where the East has meshed with the West. As a blood feud between two warring families runs the streets red, the vice capital of the world may crumble under the weight of its secrets.
Juliette Cai is the heir of her family business: the Scarlet Gang, a network of mobsters and merchants that the law cannot touch. On the other side of the city, only the Russian White Flowers match the Scarlet Gang in power--a status that Roma Montagov, the heir of the White Flowers, has personally ensured.
Although Juliette and Roma cannot stand each other, and their clans have been at one another's throats for longer than the heirs can remember, a colossal threat on both their families soon forces the Scarlet Gang and the White Flowers to work together. They must put down their guns if they are to survive, for within the depths of Shanghai, something terrible and ancient has awakened--and it is hungry.
As Juliette and Roma investigate death after death in their glistening city, they begin to uncover the truth of their blood feud. Hate and love lie side by side, and it is only a matter of time before the line is crossed. Some fates have been ordained in the stars. This is one they cannot run from.
