Audiobook Shortlist

I'd like to listen to an audiobook on my trip to Houston; it's going to be 20 hours I think.

I'm looking for suggestions for what to listen to and how to acquire said book/mp3 files for a reasonable price (because these things aren't cheap).

Other things to consider:

• I enjoy contemporary literary fiction that's a bit on the zany side (a good example would be something like Gary Shteyngart's Super Sad True Love Story).
• I'd prefer NOT to get an audiobook in place of a physical copy that I already own.(No, I'm not going to list everything I own but haven't read yet).
• I'd also like to avoid anything extremely cerebral or epic (so let's hold off on the Dostoyevsky, George R.R. Martin, or Pillars of the Earth, which is 40+ hours long!)

Here's a short list (in no particular order):

1. In the Woods by Tana French (confession: I do own this, but I can make exceptions because this is my blog and I make the rules)
2. The Financial Lives of the Poets by Jess Walter
3. The Imperfectionists by Tom Rachman
4. An Object of Beauty by Steve Martin
5. Freedom by Jonathan Franzen
6. Breakfast of Champions by Vonnegut (narrated by Stanley Tucci--but it's only 5 hours long)
7. The Savage Detectives by Roberto Bolaño (um... at 27 hours, this would lean very close to the epic side, but this author has been on my To Read in the Distant Future list)

And please, if you think any of these titles or others DON'T lend themselves to audiobook, let me know (whether from experience or reading them. I have to believe that there are some books that simply MUST be read--The World According To Garp, for example)

I also want to jump on The Hunger Games bandwagon, but everyone I talk to says I can race through it in a few days. I think I want to read them instead. I can't quite pinpoint why. At the same time, I have severe concerns that reading for pleasure is on an unofficial grad school moratorium. Maybe it can be something I save for Christmas break??

I mean, the audiobook isn't a dealbreaker for me. I've got lots of music and podcasts to rifle through, but it'd be fun to listen to a book, methinks. I mean, there's not much else going on for this drive, which will be a trek across the following states:

• Nebraska
• Kansas
• Oklahoma
• Texas

Oooh. Does anyone know of kind of road-trip-type novels? (akin to On the Road, which I've already read)
