On the fiction side I recently inhaled Dan Brown's The Lost Symbol, and Daniel Levine's The Last Ember (which was great right up until the end, where it got to be a bit too much).

On the nonfiction side of things, I'm concurrently reading The Sling and The Stone by Hammes and Kilcullen's The Accidental Guerrilla.

Next on the stack are Brave New War by John Robb, and a more in-depth re-read of Maurice's Strategikon.
