The Thousand Year Man: Book of Prizom by John Harasimo

I have had the priviledge of reading this first book of a new author, John Harasimo. 

In this novel, a man named John, after having had visions when he saw church artifacts at a museum, has a recurring dream about an unusual book in a cave. His wife contacts a Catholic priest she knows to help find out more about this book, which eventually leads John to Rome, where he finds that the book is in posession of the Catholic church, but they have kept it secret and they are unable to translate it. 

John, however can read it and this book is the beginning of his adventures related to the Book of Prizom.
It is an intriguing story leading the reader to want to know what will happen in the next books of this series.
