Hey, that was the book that turned me off CYOA - it's the one that made me realize, as a kid, that the different outcomes of your choices don't take place within a coherent world, and that there's no relationship between your actions and the result. If you turn left, than the guy your with turns out to be a Klingon spy. Turn right, and he is a loyal Starfleet officer. If you report to engineering, then the Enterprise is attacked by Romulans. If you report to the Bridge, it flies through a wormhole (not real examples since I no longer own a copy to look up). That bugged the hell out of me.
