'Two years after the events of Wyrmhole, Jack is a professional P.I. on a case to track down a missing artifact-a tablet made of a metal that cannot be identified. But when the woman he's working for disappears and his lead suspect turns up dead, Jack's investigation will lead him into the clutches of a shadowy political organization that knows the secret of the tablet.'
