I’ve been listening to the Harry Potter series on audiotape on my commute. I’m in to the fourth novel, though I usually take a break in between. Potter is perfect for listening to in the car because I don’t frequently have to “flip back” when I think I’ve missed something because Rowling is good about repeating connections that you might have missed. Not the heaviest reading (or listening), but good for audio in 30-60 minute increments.
One odd thing, though, that happens every time I listen. I start reading and even thinking in a British accent. Luckily, I don’t try to start talking in one. Though I have used the word “bloody” on a couple of occasions for emphasis.
