Tim Powers' New Novel

From the Works of Tim Powers blog:

In the winter of 1862, London veterinarian John Crawford learns that his interlude with a prostitute seven years earlier has produced a daughter. The now-reformed ex-prostitute, Adelaide McKee, has recently learned that their lost daughter is still alive—but that the girl's life and soul are in peril from a vampiric ghost whose murderous attention McKee drew in her bad old days.
