Anything Terry Pratchett or R.A. Salvatore. And even though he gets heat (and rightly so for his xanth series) Pierce Anthony holds some fond childhood memory with his incarnations of immortality. Just finished traffic by Tom Vanderbilt last week, that was a fascinating look at how and why we drive the way we do. Weeds was pretty dope(pun fully intended). Bully pulpit and freakonomics are another two that stand out off of the top of my head. I listen to most of my fiction with audio books while driving Uber.
