Query: an enjoyable vampire novel

This was an enjoyable vampire novel. Baker does a good job of building up an empathy with Ardith, the novel's central character. Via a set of nasty circumstances she goes from being a conventional-contientious student to a wild-child vampire and sets out for revenge on the people who did this to her. This is the last thing she had ever expected to happen to her - and would never have happened when she was "good". This is a novel I'm glad I've read and I'm looking forward to the sequel "blood and chrysanthemums".
