In war-torn Syria, the heroes of the SEAL Team Six series defuse an ISIS warlord's explosive plot.

After a meeting with a CIA source in Istanbul ends in tragedy, SEAL Team Six Chief Warrant Officer Thomas Crocker vows revenge. He suspects the men who attacked him and his contact are involved in the latest and most harrowing scheme SEAL Team Six is charged with preventing, in a region that grows more volatile by the day.

Syria's government is unraveling, with the alliances among rebel groups increasingly complex and ISIS dangerously in the mix. Farid al-Kazaz, aka the Fox, leads the most threatening of the ISIS factions. The Fox believes Syrian President Bashar al-Assad ordered the murder of the Fox's brother and is planning a sarin gas attack that would wreak havoc across not just Syria, but the entire Middle East. It's up to Crocker and the rest of SEAL Team Six to stop a ruthless killer and keep an explosive plan from detonating.

The SEAL Team Six series has been hailed by Special Forces veterans and members of the intelligence community as a fascinating, behind-closed-doors look at the real-life heroism of our country's bravest soldiers. Now, Mann and Pezzullo use their experience and insight to tell the story of a terrifying plot ripped straight from the headlines.
