A deadly attack against an MI6 team leaves Agent Marc Dane the only survivor--along with evidence framing him as the perpetrator. Forced to go on the run, Dane races against time to uncover the truth behind the attack and clear his name. With no one left to trust, Dane must rely on the elusive Rubicon Group and their highly skilled operative, ex-U.S. Army Lucy Keyes. A terrorist attack is coming, one bigger and deadlier than has ever been seen before. With the eyes of the security establishment elsewhere, only Keyes and Dane can stop the attack before it's too late.
