Dropped Books

What are books that you started but have stopped reading?

Ayn Rand - Atlas Shrugged
I managed to get around 100 pages in before the utter boredom struck me. I typically try to at least get 1/3 in a book before judging, but I don't want to trudge through 300 more pages to decide if I will continue reading.

You really should finish Lord of The Rings and The Silmarillion, they are rewarding eventually.

I always try and finish a book, even if I don't like it. God knows why. The only one on the list I need to go back to is Ulysses by James Joyce. I know it's a good book from the start, but he lost me a bit around the stream of consciousness stuff. I do like my full stops.
