NERD FIGHT—It's the question that has plagued geeks for centuries: SCIENCE FICTION OR FANTASY?!? Tonight, the conundrum reaches its crisis: Will you stay in Portland to see cyberpunk author William Gibson read from his latest, Zero History? Or will you trek to Beaverton to hear fantasy legend Terry Brooks spin his latest tale from the land of Shannara, Bearers of the Black Staff? THE CHOICE IS YOURS. EH
