I'm all over the map in my reading.  The more I travel - the more I read.  If I have a long flight and want to simply pass the time - I'll read a crime or spy novel. If I have time to kill while on the road that isn't sitting on a plane - then I'll go for more substance. 

 

If I'm looking for substance I just look up a list of "classics" and choose one I haven't read yet.   Lately Joyce and Hesse stuff. I usually buy used copies from amazon.  Sometimes I'll download and use the kindle app on my mobile or laptop. 

 

I'm also fond of military/historical non-fiction. These are incredibly interesting to me and are also great for insomnia - as you'll never go more than 20 pages without running into some long-winded minutiae on strategy and/or geographical details of a particular skirmish or battle.  They can happily induce the "nod-off." 

The Rick Atkinson trilogy on WWII is an amazingly informative and moving read with just the right amount of "nod-offs."
