Gorgon's Run

Life as a rural detective in the Waikato wasn't what Clem had always dreamed of. He wanted to investigate homicides not missing farm equipment. And to add to his woes his commanding officer hated him. But he was a gorgon. His vipers might hiss a bit, but he would endure.
Then he was handed the worst murder case possible. One that couldn't be solved because it had been committed by magic. The Council could never allow the existence of magic and magical creatures to be revealed to the world.
A thief's life was a better one however, and Acadia was pleased with what she did. Until the night the FBI rang her up to tell her her baby sister had been killed. Then she was plunged into a world of grief and pain. Worse, she found herself immersed in a world of the supernatural as she investigated the murder. Of wizards and gods and ancient Greek myths. A world she'd never even imagined.
And somewhere in the middle of it all were the revenants.
