This time, however, it is a mission gone wrong for Mason. He is deployed on a deniable SAS mission in war-torn Yemen, becoming embroiled in a hostage rescue that goes terribly wrong. Not only is the mission unsuccessful in rescuing Eli Drake, a priest from Norwich who has been kidnapped by the Houthi in Yemen and has been missing for three months now - Mason himself is captured after an explosion occurs during the rescue, killing one of his men as well.
As well as his own team, Mace has to work, initially unwillingly, with female CIA Agent (and Islamic scholar) Redford. Together they will need to prevent an attack that would spark a regional war and create the largest environmental disaster the world has ever seen.
It becomes a do-or-die mission for Mason and his men as they race and fight the Houthi soldiers in an exciting action-packed thriller that will keep readers glued till the last page.
