I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.
The final (so far) collection of Nick Hornby's columns from The Believer magazine and another excellent collection of commentary on books he's read. I think this is the first of the four collections where he's read a book I have (Yay!), and there are only a few of the books he's read that I'll ultimately track down myself, but it doesn't matter; I love his writing style. He's witty, irreverent, and often thought-provoking and insightful.
I'd highly recommend any of these collections to anyone who likes hearing about what somebody is reading, even if it's not something you'd read yourself. If you do share reading interests, look out: these books will devastate your TBR piles.
