When the Earth is threatened by a slowly expanding sun, mankind embarks upon a mission to send a mammoth Worldship to settle a new planet across the stars. The preternatural races step out of hiding to work with the humans to save what they can from their dying world. With the aid of the Fae, shape shifters, Vampires, and other creatures of supernatural lore, the Worldship, Leviathan, is complete one thousand years later.
Lotteries are held and only twelve million souls are selected to make the ten thousand year journey to the new world aboard the multi-generational starship.
The Worldship Files follow the cases of Knith Shade, a human law enforcement officer of the Enforcers Brigade aboard the Leviathan, five thousand years into her journey.
As the Leviathan recovers from the battle brought to it by the Artifact on the alien vessel that pierced her hull, Knith finds herself embroiled in a plot to wrest control of the Worldship and the Ka'Infinitum by two rival sects of rebel magic users.
All is not as it seems as Knith finds herself in another struggle to find the truth and do what is right.
