Mad God of the Toltecs, 2nd ed.

Is it possible that an Irish monk was the reincarnation of Quetzalcoatl?
This is an epic historical drama of the monk who was captured by raiding Norsemen, taken to the New World, where he escaped. His adventures took him past the mythical city of Cahokia (recently confirmed by archaeologists as a thriving metropolis two thousand years ago). He made his way finally to the southern lands of the Toltecs. There he was declared the reincarnated god Quetzalcoatl.
It got bloodier from then on.
