My nomination: The Poisonwood Bible.
Seriously. I tried and tried. It was highly recommended. It was for book group. I'd read some of her other books and enjoyed them. What is with this book? I struggled and finally gave up about 1/3 of the way through. Lame. Long. Boring. Nothing caught my interest. Was it the bland characters? Long, descriptive passages? I can't even remember the part I tried to read. Did anyone besides Ophra like this?
What highly recommended, much lauded, best seller did you hate?
