A choice from Tony's youth, and a first-read for Tom, Neal Stepehson's Zodiac is "a fast ride on a rough road." We discuss what worked, and what didn't, in this tale of the self-appointed "toxic-spider-man" as he uses his wits, his Zodiac, and some questionable morals to fight against illegal industrial waste. Is he an eco-terrorist, or an eco-hero? Help us decide!
