Huston, Charlie

I've only read one of Charlie Hustons books. I read Already Dead. It's a great book. The main character is a vampire that is torn between three or four different groups. He likes being a free agent and in order to do so he has to do errands for these different groups. He starts an errand for one group and leaves a bit of a mess cause the sun came up before he could finish. It all snowballs from there and ends up with the snowball in hell. I hope he makes a follow up to this book cause it was good.
