If you have both nerdy and nostalgic streaks, you need to get to Singularity & Co. at warp speed. Situated on a somewhat forlorn street where Dumbo meets Vinegar Hill, this shop specializes in vintage science fiction, fantasy, and pulp, with some espionage titles thrown in for good measure. Novelizations of Star Wars movies, Cold War killer robot stories, and yes (God, yes), the Choose Your Own Adventure Series. (We're now the proud of owners of adventure #73, Beyond the Great Wall.) (Also, be sure to ask the friendly, enthusiastic staff to show you the most mindblowing CYOA of all, in which you cannot choose the successful ending.) But the store is just part of the story: every month the folks behind Singularity & Co. identify a deserving out-of-print title and republish it. So go and support these guys --- you'll blogon us for it.
