Android Karenina
It’s gone too far, but I still love it. Although I do think these books would work better as video games.
I wonder how many copies of Pride and Prejudice and Zombies (et al.) have actually been read, though? It’s almost like that’s not what they’re for.

Schopenhauer wrote in the introduction to The World As Will and Representation that every reader knew several ways to make use of a book without exactly reading it; “it may fill a gap in his library, where, neatly bound, it will certainly look well. Or he can lay it on the toilet-table or tea-table of some learned lady friend. Or, finally, what is certainly best of all, and I specially advise him, he can review it.”
