I'm currently reading, all at the same time, Bush's Brain by James Moore and Wayne Slater, Do Androids Dream of Electric Sheep? by Philip K. Dick, Harry Potter and the Goblet of Fire by J.K. Rowling, and Dragon Wing by Margaret Weis and Tracy Hickman. I'm rereading the latter two; there's a bunch of plot details I'm fuzzy about now that I want to remember, and the Potter movie's coming out sometime next year anyway, so I hear, so I might as well have the story fresh in my mind.

Anyone who doesn't think reading is mind-expanding either isn't reading the right books, or isn't reading them the right way.
