Fans of Dave Eggers might be interested in the limited release of Sacrament, a different version of You Shall Know Our Velocity. The new version includes about sixty extra pages written by the book's other primary character, and in many ways refutes the way the story was originally told.
It's kind of annoying that this book that I liked is now refuting itself. But, at the same time it's really interesting.
I guess I already bought the first one twice, maybe the third time is the charm?
