Now those who remain coexist beneath the shelter of a domed Antarctic city, held together by a tenuous peace and an increasingly dystopian hierarchy. Any hope of one day leaving the confines of Sanctuary is little more than a fading ember. A mid-level systems operator, Ripley does his best to stay out of trouble. His best friend Felix, an irreverent half-breed shunned by society, can't seem to do the same. When Felix's family is targeted by an unjust law, there's nowhere to run. The city of Sanctuary had once been a safe haven--now it has become a cage. Ripley's desperate attempt to help his friends escape tragedy uncovers a conspiracy that envelops the last refuge of mankind in an ever-tightening net. The people of Sanctuary have never seen a sunrise. If Ripley and Felix aren't prepared to make the ultimate sacrifice, none of them ever will.
