London, 1929 â€" It isn’t easy being a fashionable flapper and emulating your silver screen heroines when you live in a poky East End terrace with your poor, widowed mother, your over-achieving sister, and such disreputable and drunken lodgers as you can find to help pay the bills, as sixteen-year-old Lucy “Lucille†Kitson can testify. However, their newest lodger â€" a young writer from the jazzy metropolis of New York â€" is far more to her liking, and it’s only a shame that he has to be concealing a secret that makes him a marked man, and endangers all who befriend him.
Pulled inexorably into a dark supernatural world, and into an even darker scientific one, Lucy Kitson finds her priorities and her survival equally challenged - hard lessons that she must endure if she is to help put an end to the “Healersâ€, their murderous nocturnal predations, and their sinister designs that threaten the lives and souls of thousands.
