Mayberry and Garrett, introduced in the thrilling Collusion, are caught in the middle of a deadly crisis with Iran in this action-packed adventure from the #1 New York Times bestselling authors. Unlikely partners Valerie Mayberry and Brett Garrett are at loose ends. The obsessive and uptight Mayberry has left the FBI on bad terms. Garrett's recent heroics have helped take a little of the sting out of his dishonorable discharge, but he's got a way to go to find redemption. When a former Iranian scientist is assassinated in Washington, D.C., the former counterintelligence agent and ex-SEAL are pulled back into the world of clandestine ops--and the fate of the entire East Coast is at stake. Joining ranks with a heralded Mossad agent, Mayberry and Garrett pursue an international killer whose motives remain a mystery. But he isn't the only threat. They uncover another planned attack--with too many potential enemies to track down and too little time. When Iran offers to help, the already tense political situation gets more complicated. Operating outside official channels, maneuvering between enemy powers, the two know they must tread carefully to prevent an international incident and keep themselves alive. Is Iran playing us for fools, again? Or are they undermining some other enemy? Can a dysfunctional Washington do the right thing to protect the country? Will political infighting at the FBI grind the investigation to a halt? Will Mayberry and Garrett find the truth before innocent lives are lost?
