Kill All Angels

After the events of the first two books of the Vicious Circuit series, Carey and Randall reached LA during the early '80s punk scene, which was heavily mixed up with Chinatown. A young Chinese girl with silver hair is the Empty One that seems to run things there, and her ex-lover, an Empty One named Zang, has apparently turned against them and may or may not be on Carey's side. In modern times, Kaitlyn and company have also returned to LA because her powers have been growing and she has been having visions that may be telling her how to kill all of the angels. The downside being that they have to find a new one, first—and LA is the only place they know where to do that.
