Of all the books you own, what's the one which a) you have never read, and b) is least likely out of all your books to ever be read, but c) you're unlikely to get rid of?

Mine:
The Origin of Consciousness in the Breakdown of the Bicameral Mind, by Julian Jaynes.

@passenger Weirdly I both own that book and have read it. I have a small collection of books by cranks and crackpots.

For me it's probably The Handbook of Unfulfilled Bible Prophecy by Pastor C. Donald Chrysler. TBH I only bought it because I misread the cover and thought it said Fulfilled Prophecy. Then I realized it was published in my hometown and the author attended a now-defunct Bible college in my old neighborhood. Now I have to keep hauling it from apartment to apartment forever.
