Finished reading The Brothers K last week (among a bunch of other stuff). This easily goes on the list of best novels I have read. It was certainly better than any novels I read last year. Were it not so plainly (though not faithfully) based on a Russian novel, it would be a contender for the mythical Great American Novel. Stan Hauerwas recommended it to me (though I'm sure my brother had done so years earlier as well), by saying it was about the only important things in life: God and Baseball.
On the not so serious side I also recommend Noah Adams' (of NPR fame) little book Piano Lessons, a diary of the author's attempts to learn piano as an older adult. Includes plenty of piano trivia which was new to me. I'm halfway through, but it has been engrossing so far.
