John Traveller never asked to be ripped from his life as a police detective on Earth. He definitely never expected to find himself trapped inside a patchwork alien city of magic and technology, locked down under an impenetrable dome. But when a high profile death rocks the citizenry of GreenGrass, Traveller is forced into the middle of a brewing civil war between the city's two dominating factions.

Racing beneath the city's twin red moons, on a search for a cloaked stranger, Traveller and his team consisting of a pacifist demon, a cast out demi-god, and a telepathic female, find themselves drawn into dark alleys and guarded secrets, facing bestial street predators, techno-assassins, amphibious conmen, and a vampire acting troupe.

The answers they discover may save their new home or bring the walls of the dome crumbling down around them all.
