"What happens when a single moment changes everything? For seventeen-year-old Cheney, life on earth exists only in history books. The life he and over one thousand other people know is 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<U+2019>s nurtured them for so long becomes responsible for their destruction." --From the publisher.
