The last page: Heather, The Totality
Heather, The Totality is ruined by its ending. Weiner makes it clear that Bobby is out to harm Heather, whether through rape, murder, or some kind of deranged fantasy where they run off together. She notices his attention, and is at the right age to find a mysterious bad boy alluring, at least in an abstract sense. When her father Mark senses that, and intuits the threat Bobby represents, he grows incredibly paranoid, putting another strain between him and Karen. At the climax, Mark pushes Bobby out a window, killing him. He confesses to Karen, and the book ends with their decision to keep this secret, as the death is ruled an accident.
