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.

I got Hitchhikers Guide to the Galaxy.
The complete trilogy in five parts.
I CANNOT get past the fifth part when he gets back to England and it get romanticy.

Someone tell me if it get fun again...
