Note: No spoilers here. I wouldn't do that to you.
On something like chapter 7 of 1Q84. My friend's on chapter 3. Allison Hiroto, Marc Vietor, and Mark Boyett read the audio version quite impressively (at least the first two do; I haven't heard Boyett yet). I especially like Hiroto's middle ts, which sound like /t/ instead of the usual /d/ you say and hear (say "little" aloud, as you normally would). Her words have a slight separation between them, not the usual carrying over of a final consonant into the initial sound of the next, vowel-sound-staring word. Her speech sounds like the tapping of fingernails on glass, one of my favorite sounds, it turns out, as long as it varies in its regularity. The end of Marc Vietor's sentences feel like warm sand, getting into your crevices, in a good way. Listening to this story while walking around Kaifaqu is a great way to spend an afternoon.
