I'm rereading two books: The Amulet of Samarkand and The Golem's Eye.
They're part of the Bartimaeus trilogy by Jonathan Stroud, and they are all excellent. I'd highly recommend the trilogy for those who enjoy fantasy, magic, spiritual entities, or amazingly sarcastic characters (Bartimaeus himself). Actually, I highly recommend it in general.
I'm reading Into The Wild by Jon Krakauer. I'm actually reading as a summer assignment for my AP Literature class. It might sound like a drag, but I actually find the story interesting.
