The supernaturals have taken over the world and established kingdoms. Each country has been split to accommodate each supernatural; sections go to the vampires, sorcerers, shapeshifters, and werewolves. And the humans? They are the commoners that make up the rest of the population; slaves to the supernaturals. They are workers in the castles, owned by high-ranking supernaturals, named the Royals. Such tales of Royals falling in love with the humans have already permeated the world, love-bound tales doomed to fail and hope-driven stories of everything falling into place. We are here to hear the story of one such human, a castle-slave boy by the name of Niall, and his Moon-chosen mate, a Royal. A prince.
