Tuscany, 1096 AD. Luca, young heir to the title of Conte de Falconi, sees demons. Since no one else can see them, Luca must keep quiet about what he sees, or risk another exorcism by the nefarious priest Ramberti.

Luca also has dreams-dreams that sometimes predict the future. Night after night Luca sees his father murdered, and vows to stop it coming true. Even if he has to go against his father's wishes and follow him on the great pilgrimage to capture the Holy Lands.

Far away in Cappadocia, Suzan has dreams too. Consigned with her mute mother to a life in an underground convent, she has a vision of a brown-haired boy riding through the desert. A boy with an ancient book that holds some inscrutable power. A boy who will take her on an adventure that will lead to places beyond both their understanding.

Together, Luca and Suzan will realise their true quest- to defeat the forces of man and demon that wish to destroy the world.
