I think this might normally be categorised as teenage paranormal romance but I have to say that this is so much more. It reveals the underbelly of Edwardian life, where, for example, a girl in her undergarments is more shocking than murder!
I found all the spiritualist/medium parts fascinating.
Violet assists her mother, a fake medium, only to discover at 16 that she has the true gift and she can suddenly see ghosts and communicate with them. This leads her into the dangerous situation, where she feels impelled to assist a ghost in revealing her murder, exposing the murderer and saving, her living, sister from the same fate.
I found this book fast paced and well written. I read it in 24 hours on holiday and found it hard to out down
