Dearest Miss Snark:
I'm working on a freelance piece about books by famous authors that they wish they hadn't written. Basically, stuff by famous authors done under pseudonyms (Dan Brown did a humor book under the pseudonym "Danielle Brown"), old random stuff by famous authors (a book on Space Invaders by Martin Amis) or just really old stuff that looks pretty foolish now ("How to Talk to Just About Anyone about Anything" by Barbara Walters.")
Any spring to mind?
Miss Snark is busy dusting her rubberplant so she turns this one over to the accumulated wisdom of the Snarklings!
Any contributions for our querier?
