Despite the fact that grad students generally don't have much time to read, I say "Screw that!" and read for fun anyway.
In the last year or so, it seems like I've been reading A LOT of non-fiction, and I am kind of sick of it. I am slowly slogging my way through Collapse by Jared Diamond, which is good, but way too detailed, depressing, and pretty dry. (How can it be good, then? The information in it is really thought provoking.)
I am now in the market for some good fiction. I like to read relatively smart, yet accessible fiction (what some people call "middlebrow."). Possession, by A.S. Byatt is a great example of this. I tend to like books that have won the Booker Prize (now called the Man Booker Prize). Possession won, and so have The Remains of the Day and Life of Pi, both of which I enjoyed tremendously. I also read fun chick lit, when I am looking for something lighter. My all-time favorite in this category is the duet of Bridget Jones's Diary and Bridget Jones: The Edge of Reason, but other good ones are Carrie Pilby by Caren Lissner, Diary of a Mad Bride by Laura Her-Name-Eludes-Me, and most recently, The Devil Wears Prada by Lauren Weisberger (no, I haven't seen the movie yet, but I want to because Meryl Streep is really good).
So far, on my list, I have Prep by Curtis Sittenfeld, On Beauty by Zadie Smith (it's a retelling of Howards End by E.M. Forster, another book that I enjoyed), and Never Let Me Go by Kazuo Ishiguro.
I am looking for more. Any suggestions?
