A meeting of two worlds. A tale of forbidden love. A chronicle of heresy and crime. Set in the era of the Third Crusade, The Cult follows the fates of Elise, Edmond, and Martin, three friends threatened by a sinister Gnostic cult. One by one, they come to Arab-Norman Sicily, a rich and brilliant realm where Christians, Jews, and Muslims live in peace. As their imperiled lives unfold, all three friends struggle against both the evil of the cult and the oppressive prohibitions of their time.
