There are a fair number of holograms in The Warhol Gang, but they’re all fairly contained. I wanted the book to feel slightly futuristic, but I didn’t want it to feel like full-blown sci-fi, so I restricted the fantastic things to holograms in the neuromarketing pod and hologram theme park disasters, so people could relive the World Trade Center attacks and things like that. I worried if there were too many holograms and other technological delights in the story, people wouldn’t believe it. Of course, shortly after The Warhol Gang came out, real life has turned it into a historical fantasy….
