"Gutted by the ruthless power brokers known as the Combine, the Rubicon Group is a shadow of its former self, its founder Ekko Solomon missing presumed dead and the members of its private security and intelligence team in hiding, framed for a terrorist atrocity they did not commit. For ex-MI6 officer Marc Dane, his friend and colleague Lucy Keyes, and the survivors of Rubicon's Special Conditions Division, the future is bleak. With no support and no backup, they are living on the edge, and the walls are closing in - so with nothing left to lose, the team will risk everything in a last ditch gambit to strike back at the Combine and bring them down...once and for all."
