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?
Baldur’s Gate: Bhaal must be stopped! by Philip Athans. The utterly awful novelisation of the first Baldur’s Gate game. It’s complete and utter trash, and I feel I must contain it in my apartment, lets anyone else read it.
(The second and third books are also trash, but like… marginally better.)
