Cool, I'd be interested to hear what you think of it when you finish it. I read it more than a decade ago and really loved it at the time. The older I get, the more I feel like the rest of Danielewski's work is not so great, but when I think back on House of Leaves, I still find the concepts and the whole approach to be pretty exciting. I've been thinking I might re-read it at some point, just to see if it still holds up.
