What happens when a single moment changes everything? For seventeen-year-old Cheney; life on earth exists only in history books. He and more than one thousand other people have known life only aboard the Plexus spacecraft: self-contained; systematic; and serene. But that was before the radiation wave. Now Plexus has suddenly turned on them; becoming a terrifying and unrecognizable force. As the crew dwindles under attack; Cheney and his friends need to fight back before the ship that’s nurtured them for so long becomes responsible for their destruction.
