Journalist Liv Adamsen escaped the highly-secretive Citadel and now lies in isolation, staring at hospital walls as blank as her memory. She feels possessed by an unexplained sensation and plagued by whispers only she can hear: 'KuShiKaam', the key. To others the meaning is clear. For 'the Ghost', a mercenary in Syria, Liv may hold the key to history's most powerful secrets. For the brotherhood of monks, she may be their only chance at survival. And for a powerful faction in the Vatican, her very existence threatens the success of a desperate plan. Hunted from Turkey to New York to the deserts of the Middle East, Liv races to uncover a revelation dating from the creation of man in this electrifying follow-up to the international bestseller Sanctus.
