Author leveraged compelling approach to this historical fiction by leveraging a deep understanding of history from medieval times to contemporary periods. The use of multiple plot lines through a web of mysticism generates a fantastic read. I can see this becoming a series of books, and/or films. My teenagers believe it should be made into a game. Read all 700+ pages in less than a week, difficult to put down. Hope Quentin Grady continues to write and expands upon this book for the benefit of his followers.
