I just binged the entire Hitchhikers Guide series, so I took a couple of weeks off after finishing "And Another Thing" to digest everything.
This week I started listening to New York 2140 by Kim Stanley Robinson.
This is the first audio book I've listened to with a cast of people each doing characters, and it's a bit different, so I'll see how I feel about it in the long run.
My desk book (for when I take small breaks and want a short story) is still The Martians by KSR, although I realized I never finished Asimov's The Complete Stories Vol 1 that used to be on my desk, so I think I may pull it back out next.
