I've almost always got a book lying around somewhere that I'm somewhere in the middle of. For example, right now I'm reading the fourth book in R.A. Salvatore's Legend of Drizzt series. I like to read just about any fantasy or science-fiction book, which is good because I have this one friend who always lends me books, and those are the only kinds of books he has.
After having read what I just wrote, I must ask you to please forgive the sloppiness of this post. I'm waaay too tired right now to actually write anything coherent, so I'll try editing this post tomorrow when I'm more awake.
