The Soprano Sorceress series by L.E. Modessitt. He's one of my favorite authors. I've read all the Recluse books and just started this set. (Is it Recluse or Recluce... I can't ever keep it straight)
And, in preparation for Kingdom of Heaven coming out this weekend, I stumbled across John J. Robinson's Dungeon, Fire, and Sword in the library. It's a history of the Templars, and so far it is very good.
