From #1 New York Times - bestselling author Catherine Coulter, the explosive new addition to the remarkable thriller series featuring Nicholas Drummond and Mike Caine.

FBI agent Nicholas Drummond and his partner, Mike Caine, are deep into an investigation of COE - Celebrants of the Earth - a violent group known for widespread bombings of power grids and oil refineries across the country. While investigating a tip from a civilian who's overheard about a possible bombing plot, the Bayway Refinery in New Jersey explodes. Nicholas and Mike race to the scene and barely escape being killed by a secondary device.

Returning to the civilian's home to continue their interrogation, they discover the tipster - and the FBI team left to guard him - dead. While Nicholas calls in the assassinations, COE strikes again, this time launching a cyber-attack on several major oil companies and draining their financial and intellectual assets.

But COE has been infiltrated by a deep-cover counterterrorism agent named Vanessa Grace. A bomb-making expert, Vanessa must leave COE and join forces with Nicholas and Mike to stop the organization's devious plan to assassinate the president. But there's an assassin on the loose who could tip the scales in COE's favor, and no one knows his ultimate target, or who has contracted his services.

Working with the CIA, the Secret Service, Mossad, MI-5, and even Savich and Sherlock, Nicholas and his team put their lives on the line to prevent another conflagration - and save the President.
