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 i have actually squirreled away so many books for retirement i've forgotten what they are, half the books i own i haven't read. I come from a long lived family so will probably end up reading everything if my days come to a natural conclusion.
