Replying to Audiobooks

I have to drive 12 hours this weekend and I've run out of good books on tape for the car. I have a long list of books I want to read but most of them wouldn't be great to listen to, since in the car it's nice to have something less involved and more mindlessly entertaining where the specific language and sentence structure isn't itself a special and noteworthy aspect of the book. I recently listened to the Millennium trilogy and loved it, so something along those lines. I was thinking the Hunger Games but I read half of the first book and didn't get into it, but something action packed and easy listening like that.

Any suggestions?
