Meet Matt Richter. Private eye. Zombie.
His mean streets are the city of the dead, the shadowy realm known as Nekropolis. And in this first case, Richter must help a delectable half-vampire named Devona recover a legendary artifact known as the Dawnstone, before it’s used to destroy Nekropolis itself. That is, if he can survive the myriad horrors that infest the city itself.
It's a bit silly, a bit tongue in cheek but quite entertaining. If Tim Burton wrote a novel it would be bit like this.
Its no award winner but I quite enjoyed it.
There are some free short stories based on the same characters on his site - http://www.timwaggoner.com/index.htm
