Query: A faith builder

Having read all of Lawhead's books, I thoroughly enjoyed Byzantium. Though not a fast read, it has all the elements that makes Lawhead's works brilliant - superb writing, adventure, and a spiritual message. Byzantium's story line takes you just about everywhere. And what I enjoyed most about the book was how I was able to relate with Aidan (though I've never faced the trials he had to endure!). Byzantium is a faith builder for the believer.
