I can't really stay focused too well so I switch back and forth between different books all the time and will often stop in the middle of a book and not read any more for a long period of time.
Right now I'm reading these:
The Lord of the Rings: The Fellowship of the Ring
The Prophet of Yonwood (the 3rd book in the City of Ember series)
I, Robot
The Hitchhiker's Guide to the Galaxy (and I've only had 20 pages to go for the past month)
and in school right now I'm reading The Scarlett Letter in English class and The Night in Holocaust studies. The Scarlett Letter's pretty boring but The Night is pretty good
