If you've never listened to an audiobook, I highly recommend the 'Across the Nightingale Floor' audio presentation. The readers are fantastic, the storyline is wonderful, and you'll end up with a hankering to find more ancient Japan to explore.
Faboo stuff, and there was just a fourth book released (but, alas, unlike the other three, there are different readers this time).
Anyway, all are available through audible.com (which is how I end up listening to all of them through my iPod).
