I'm skipping the interview part but thought it'd be interesting to post my ten titles. Perhaps you'd care to respond and include your own list? Could be kinda fun to compare notes.
I haven't included the Bible though it's first and foremost, and supercedes any such earthly compilation I might cobble together.
