Ian Fleming meets John Le Carre in this international bestseller and world-spanning espionage thriller.

Marc Dane is an MI6 agent at home behind a computer screen, one step away from the action. When a brutal attack on his team leaves Dane the only survivor—and with the shocking knowledge that there are traitors inside MI6— he's forced into the front line.

Matters spiral out of control when the evidence points toward Dane as the perpetrator of the attack. Accused of betraying his country, he must race against time to clear his name. With nowhere to turn to for help and no one left to trust, Dane must rely on the elusive Rubicon group and their operative Lucy Keyes. Ex U.S. Army, Keyes also knows what it's like to be an outsider, and she's got the skills that Dane needs.

A terrorist attack is coming, one bigger and more deadly 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.
