The narrator of this book, Bruce, has an obsession. He lusts over Aviva, a new student at the elite Auburn boarding school. He yearns for the highly sexualized relationship he imagines Aviva has with her boyfriend, Seung. Bruce is a Holden Caulfield wannabe as a narrator. The same broken stream of thought. Is anything real? How much exactly is Bruce's imagination? It's difficult to tell in this novel. Bruce mimics Holden in his feel, but Holden was never this crass.
At the end of the novel, you have a sketchy idea of what the real events that transpired between Aviva and Seung. The rest is high school gossip and Bruce's frenzied imaginations of what sex is like between the couple.
