Eighteen-year-old Juliette Cai has returned from America to her native Shanghai. As heir to Shanghai’s Scarlett gang, this is her chance to prove her worth, and maybe display a bit of her ruthlessness, too.
As a girl she was betrayed and sent away years earlier. And it was all because she loved Roma Montagov, the heir to Scarlett’s rival gang, the White Flowers. But proving her worth isn’t about some past fragile feelings or a lust for violence; it is a way to ensure her safety and protect her family.
In the meantime, a mysterious monster has appeared. It comes out of the Huangpu River and spreads infection. The infection, like lice, attacks anyone regardless of gang or political affiliation. Once sick, people go crazy and kill themselves by tearing out their throats with their own hands. The madness spreads without an answer until a shadowy dealer shows up with a cure. However, that innoculation only works for some.
A monster that disappears into the water, a magical vaccine, a mysterious dealer. It seems like the only way to find a solution that can stop all the madness and cover all of Shanghai is to approach the White Flowers gang and work once again with Roma Montagov. He may be the only man Juliette has ever loved, but that’s of little concern now. Thanks to his past betrayal, she feels more loathing for him than anything else.
But as the bodies pile up and fears rage, Juliette and Roma must agree to set their grudges aside. They must work together, even if just in secret. For if they can’t find a way to end this terror, there will be no city left for either gang to rule.
