These powers have only grown stronger with the couple's disappearance. Nothing is heard from them for quite some time, until Sabine asks Matthew Sedon, a young archaeologist working in Egypt, for help. As Matthew is reluctantly drawn into the intrigue, he finds encouragement from his strong-willed and passionate girlfriend, Isabella de Reims. Miles away in Paris, Isabella struggles with haunting glimpses of mythic landscapes and surreal creatures that come to her in waking dreams. Slowly Matthew and Isabella realize that once ajar the door to another world cannot be closed at will.
