From M.T. Anderson's YA novel about a future in which commerce and relationships are driven by a chip in everyone's brain. It's a quick, sharp read, full of dark humor and incisive observation about the ease with which culture erodes:
Marty had also gotten a Nike speech tattoo, which was pretty brag. It meant that every sentence, he automatically said "Nike." He paid a lot for it. It was hilarious, because you could hardly understand what he said anymore. It was just, "This fuckin' shit Nike, fuckin', you know, Nike," etc.
Everything was not always going well, because for most people, our hair fell out and we were bald, and we had less and less skin. Then later there was this thing that hit hipsters. People were just stopping in their tracks frozen. At first, people thought it was another virus, and they were looking for groups like the Coalition of Pity, but it turned out that it was something called Nostalgia Feedback. People had been getting nostalgia for fashions that were closer and closer to their own time, until finally people became nostalgic for the moment they were actually living in, and the feedback completely froze them. It happened to Calista and Loga. We were real worried about them for a day or so. We knew they'd be all right, but still, you know. Marty was like, "Holy fuckin' shit, this is so Nike fucked."
