In this cautionary book, YA (Young Adult) author Anderson takes a familiar element of cyberpunk fiction and applies it to American teenage culture in the far future. In this vision of "wetware", brains can be directly wired to the internet, creating a streaming"feed" of audio, video, and text that operates as a kind of second level of consciousness. People can mentally IM each other across the room, and as their brains process what they see, they are bombarded with targeted advertising. We are introduced to this future via narrator Titus and his cohort of friends. They are archetypes of vapid teens, blindly following the latest fashion trends (and in this ultra-wired world, girls change hairstyles by the hour), purchasing the latest clothing off the feed, getting wasted at semi-legal "malware" brain-scrambler sites, and generally ignoring anything beyond their immediate superficial concerns.
When the group goes to the moon (kind of a mix of Las Vegas and Daytona Beach) for spring break, they encounter the dark side of the feed -- the possibility of getting hacked (since the feed is wired directly to their brain, this can have calamitous effects). Titus also meets and befriends Violet, a home-schooled girl who takes a shine to him and wants to join his circle of friends. It's not really clear why a girl as smart and allegedly beautiful as Violet would be interested in the nice, but not particularly bright or introspective Titus, but their relationship becomes the basis for Anderson's rather obvious anti-consumerist message. Violet is the bright alternachick who'd figured out that the feed's main purpose is to get people to buy stuff, while Titus is the nice, but not too deep dude who just wants to get along and have a good time. His inability to accept her inconvenient truth plays out plausibly, as Anderson wisely avoids any cheesy moments of realization or transformation. But this is undercut but all the characters' two-dimensionality and the story's overall lack of nuance.
There's a running background story about unrest around the world resulting from America's massive consumption, and some unexplained lesions that are appearing on everyone's skin, but Violet is the only one paying attention as the group does the standard teenage stuff. The book does a very convincing job of sketching the lives of future teens, with particular attention to language (for example, instead of saying "Dude!", people say "Unit!"). Chapters end with blasts of the feed, giving a keen sense of the barrage of marketing directed at the characters. Unfortunately, the teens who are most likely to read a dystopian semi-cyberpunky novel about the dangers of capitalism and consumerism are the ones least likely to need to hear the message.
