Ryan Cross is the most popular senior boy at Violet and Finch’s school and. Up until a month or so before the novel begins, he was Violet’s boyfriend. Violet describes Ryan as stable, reliable, and all-around perfect, and Finch agrees with this. However, Violet also shares that Ryan isn’t actually perfect: he’s a “kleptomaniac,” compulsively stealing all sorts of items (even things he doesn’t really want). Violet breaks up with him in part because he’s unable to effectively support her in her grief, and Ryan spends much of the novel trying to get back together with her. Though they date briefly while Finch is missing, Violet breaks things off for good after Finch dies. However, the two remain friends, and Ryan joins Violet and a group of classmates on the top of the Purina Tower to honor Finch’s memory.
