I'm on a long re-read of the R.A. Salvatore Drizzt series. Right now it's: The Orc King (Transitions, Book1 - #17 in the wider series).
I was on vacation for a little over 2 weeks and went through 6 books on the trip. Trains, planes, coffee shops, and hotel room before bed. It's surprising how much reading can get done in-between exploring new cities.
