On a Santorini cliff high above the great caldera of that sunny, serene Greek island, Captain Beth Walker marries CIA agent Matt Price. After the ceremony, her nephew, Steven, leaves for nearby Mykonos, only to be assaulted and kidnapped. When Arab television later shows Steven kneeling blindfolded before an executioner, the CIA sends Beth and Matt after him. The chase moves to Kurdistan, where avatars and wolves confront magic ravens and the Cult of Angels.
