Sun-dwellers are foul monsters that eat a human's flesh from their bones...or so sixteen-year-old Lyra has always been taught. To keep their citizens safe, her colony seals itself into the vaults by day. Moonwalkers are horrible beasts that feed on the blood of men...at least, that is what Perseus was told. The only sure survival for his people is to lock themselves into their repositories each night. Both labeled as undesirable by their respective kinds, a fated meeting in the forbidden forest offers Lyra and Perseus an unexpected chance at happiness. If they can overcome their own prejudices and discover the truth about one another before time runs out. Can the sun-dweller and the moonwalker learn that when reality is distorted by hate and terror sometimes the only thing to truly fear is fear itself?
