Bullet [EPUB ebook] 

I am back in St Louis and trying to live a normal life – as normal as possible for someone who is a legal vampire executioner and a US Marshal. I have my lovers, my friends and their children, school programs to attend. In the midst of all this ordinary happiness a vampire from my past reaches out. She was supposed to be dead, but the Mother of All Darkness is the first vampire, and it’s hard to kill a god. The Mother of All Darkness believes that the triumvirate created by master vampire Jean-Claude with me and the werewolf Richard Zeeman has enough power for her to regain a body and to emigrate to the New World. But the body she wants to possess is already taken … And if the Mother of All Darkness can’t succeed in taking over my body for herself, she means to see that no one else has the use of it, ever again.
