City of Lights (City of Whispers #3‪)‬

The vampire outbreaks in New York and London are over, most of the world believes the vampires have died out, and the human survivors of the epidemics have been released from quarantine. Believing that it is only a matter of time before Desmond hunts her down, Ailis moves from one city to another, trying to get to Desmond before he can get to her. But, as she loses herself in her obsession, Ailis begins to feel she has more in common with the one she's hunting than with her fellow humans.
