Which comes to
THE VERY DIFFICULT LIBRETTO MEME:
Name three books that would make very difficult subjects for an opera libretto which you'd nevertheless like to see and hear on stage:
(1) James D. McCawley's The Eater's Guide to Chinese Characters. ("The purpose of this book is to enable non-Chinese who enjoy Chinese food to better exploit Chinese restaurants."*)
(3) Walter Abish's Alphabetical Africa. (A novel in 52 chapters, the first of which uses only words beginning with "a", with each following chapter adding words beginning with the next letters of the alphabet until the 26th chapter has words available beginning with all 26 letters, and then reversing the pattern over the remaining 26 chapters.)
Your turn, now.
*I had to include a food-related text, but Baker's The Gentleman's Companion, the obvious choice, is just not difficult enough; I also considered The Joys of Jello, an interesting feminist document, and the brutalist The Roadkill Cookbook, rejecting both for lack of opera-plot-level conflict.
