My friend Zach Weiner writes the incredibly funny and hugely popular web comic Saturday Morning Breakfast Cereal (link possibly NSFW). He just wrote a book called Trial of the Clone, which is a "chooseable path gamebook", like an adventure where you can choose your path. Say. I happened to be at his booth when the very first printing of the books arrived. This is literally the first copy Zach got his hands on, and he was really, really happy to see it.
