People often feel like they are making their own choices, striving for a specific goal. The heroes of the novel think so too. But gradually they realize that they are driven by higher forces, commanding an infinite number of worlds. It is these forces that force the heroes to rush to the Holy Land: in one of the worlds - on a spaceship, in the other - with foot pilgrims who went to Jerusalem from France during the Crusades. The true purpose of the dangerous journey will be revealed to them only at the end of the journey. Only by touching the symbol of the power of God, capable of transforming Time and Space, will they understand the meaning of their existence.
