This is the second book in the Anita Blake series. In this book, someone wants Anita to raise a zombie so old that she would need a human sacrifice to do so, Anita refuses, so that person is out to convince her that she needs to do it. Anita is also trying to avoid Jean-Claude, the new Master of the City (vampire), who wants Anita to be his human servant. She is also threatened by a voodoo priestess who wants Anita to join her in a 'business venture.' There is plenty of action, from being assaulted by muscle bound bodyguards, to being attacked by zombies.
This is one of my favorite series, it progresses well, and is quite entertaining.
