Oh, this is a FUN thread!!
Let's see...
I read about a third of
Mists of Avalon and simply could not finish it. I'm not particularly interested in the Arthurian myths anyway, and the characters simply didn't appeal to me. MZB has a nice writing style, but IMO, this story was just way, way, way, way too long.
When I was a teenager, someone recommended
The Thorn Birds to me. I read the first half-dozen pages and hated it, threw it down, never finished it.
My brother recommended
Good Omens over and over to me, and even loaned me his copy. I love Neil Gaiman, but I just can't get past the first chapter of this book. I don't hate it, I just can't get into it.
The Bible-- ha! There's another one. I can't make it past Genesis without falling asleep.
Thomas Hardy. Woah. The only writer in high school English classes I simply could not read. Long-winded, tedious, tiresome! I finally had to read the Cliff Notes to find out how
Return of the Native ended, the only time I ever did that. He was like a literary sedative.
I only picked up
Lord of the Rings this year. Before that, I was literally the only one of my friends who had not read it. I saw
Fellowship in the theater last January, and was aware that about 60% of the story was going right over my head. I got the books as presents, and finally read them. I'm glad I did: it was one of the best reading experiences of my life. I didn't want it to end! I picked up
The Hobbit almost right away, because I didn't want to leave Middle Earth.
OTOH, I picked up the first Harry Potter book in January 2000, and have been rabidly hooked ever since. No prodding at all was needed on that one!
Finally, my top contender for "book I would not use as toilet paper" goes to Caleb Carr for
Killing Time. What an utter piece of donkey shit! It's like a horrible attempt at sci-fi/ speculative fiction, penned by a seventh grader with no talent. The faults of this book are almost without number: a lame plot, utterly unmemorable one-dimensional characters, way too much exposition, too little dialogue, and an oh-so-convenient "deus ex machina" ending. All the interesting stuff is glossed over, while he focuses endlessly on pointless garbage. (Don't even get me started on the Mary Sue of a lead female character.)
And it's even more baffling to me that this crap came from the same guy who wrote the terrific
Alienist and
Angel of Darkness, both of which I would recommend without reservation to anyone. Go figure!
