Forensic entomologist Dr Vanessa Marwood isn't in Sydney for the sights. She's hunting for answers - and Detective Finn Harper, renowned cult expert might have them.

His expertise could be the key to exposing a shadowy organisation with ties to Vanessa's hometown and the glittering elite of New York.

As the media and police force reach a frenzy, Finn and Vanessa must pool everything they know - and risk their own safety - to find whoever is behind these sick, statement murders, that are only the beginning...
