I decided to get a "mystery" book and some sort of historical fiction at the library. Both sound good and I'm particularly excited about The Battle for Duncragglin-it's a story about a boy who visits this castle that allows him to travel back in time to discover what happened there. It kinda reminded me of Timeline by Michael Crichton (also a major motion picture).
