For me, it’s Jude the Obscure. That book is easily the worst book I have ever read, without a single redeeming quality, other than that it finally ends. I only finished it because Far from the Madding Crowd was so damn good.
But really, Jude is the gold standard of awful books, in my opinion.
What’s your so-awful-it-deserves-shelf-space book, if you have one?
Or am I just weird?
TRIGGER WARNING by William W Johnstone except it’s not by him cos he’s dead it’s actually by his illiterate Trumpist nephew. My partner and I get drunk and read chapters to each other, doing the voices we know the author was thinking in his head when he wrote it: https://www.goodreads.com/book/show/37507173
