The Dresden Files are all fun reads! The audiobooks are particularly good too, with James Marsters doing a wonderful job!
I'm finishing up Rhythm of War in the Stormlight Archive series. It's my first foray into Brandon Sanderson, and I'm enjoying it so far, but there's so much that I don't know how into the Cosmere I'll end up going. On the non-fiction side, I'm reading Nate Silver's On the Edge and trying to work my way through my third (maybe fourth?) reading of Gödel, Escher, Bach by Douglas Hofstadter, which I always grasp a little bit more of each reread.
