This is the first book in the series and I really enjoyed the early books, readers should be aware that the content of later books changes significantly. The early books were urban fantasy with the focus more on the zombie raising, crime solving etc where as the later ones focused on her relationships

'I don't date vampires. I kill them.'
My name is Anita Blake. Vampires call me the Executioner. What I call them isn't repeatable.
Ever since the Supreme Court granted the undead equal rights, most people think vampires are just ordinary folks with fangs. I know better. I've seen their victims. I carry the scars ... But now a serial killer is murdering vampires - and the most powerful bloodsucker in town wants me to find the killer.
