The greatest science fiction or fantasy novel is the one that speaks to you at the time you read it. So there's nothing wrong with giving up on a book halfway through, even if it's considered one of the genre's all-time classics. Which acclaimed science fiction or fantasy book could you not manage to finish?

Please include a book cover or other image for this classic — and if it's not obvious, please let us know the title, and when you quit reading.
