I think all good narration contains an element of mystery and suspense. If it didn't, if the storyline were predictable, we would have no interest in reading it.
It's an America with strange mythic depths. I see it as a distorting mirror; a book of danger and secrets, of romance and magic. It's about the soul of America, really. What people brought to America; what found them when they came; and the things that lie sleeping beneath it all.
