Could you eat one food for your entire life? Jonah has been imprisoned at Cydonia 6 and eating broccoli for as long as he can remember. Beatings, broccoli, and mind-numbing routine are all that he knows. Like the rest of the planet beyond the prison camp’s towering fence, his purpose in life is a mystery—until he discovers a note written by a former inmate that warns of doom. Something lurking in the basement of the prisoners’ barracks is taking them one-by-one. Escaping from Cydonia 6 would mean a terrifying journey into the unknown and walking through a den of ravenous monsters; but Jonah doesn't want to be taken next.
