Quentin Jacobsen

The protagonist of the novel, and the novel’s narrator. The story is told in the first person through Quentin’s eyes. Quentin, nicknamed “Q,” is a high school senior who is ready to graduate and go off to college at Duke. He is a genuine, normal, somewhat nerdy, but essentially well-adjusted kid. He does well in school, has good friends, and seems to be on track for a successful life. The major drama in Quentin’s life is his obsession with Margo, the cool girl who lives next door.

Margo Roth Spiegelman

Quentin’s next-door neighbor, and Quentin’s long-time crush. Quentin has known and liked Margo since they were children. In Quentin’s descriptions of her, Margo is the stereotypical cool girl. She’s a queen bee at school, but she’s also somewhat of a rebel, and cultivates an air of mystique around her through her adventures and wild stories. Margo is also quite self-centered, and she holds deep grudges.

Ben Starling

Quentin’s best friend. Ben and Quentin tell each other everything. They are both near the bottom of the social totem pole, which is how they first became friends. Ben is much more outwardly obsessed with his image and his place in the high school hierarchy than Quentin is. Although Ben plays along with Quentin’s obsessive scheming about Margo, Ben is convinced that Margo is being a drama queen, and doesn’t get as emotionally invested.

Quentin and Ben’s other best friend. Radar’s parents have the world’s largest collection of black Santa figurines. Radar spends most of his time obsessively editing Omnictionary, a Wikipedia-like crowd-sourced encyclopedia.

Lacey Pemberton

One of Margo’s close friends, and one of the popular girls at school. Margo is mad at Lacey because she thought that Lacey knew that Jase and Becca were sleeping together, but it turns out that Lacey didn’t know anything. Lacey gets really worried about Margo and joins Quentin’s quest to find her.

Mr. and Mrs. Jacobsen

Mr. and Mrs. Spiegelman

Margo’s parents. Unlike the teenagers in the novel, who are in awe of Margo and idolize her every move, Margo’s parents are frustrated with what they perceive to be bratty and rebellious behavior. Instead of trying to help her, they back away from these issues.

Detective Otis Warren

The detective assigned to search for Margo. Quentin trusts the detective and tells him as much as he knows. The detective often speaks in metaphors, referring to Margo as a “balloon” with cut strings. He is convinced that Margo isn’t particularly special, but rather one of many teenage rebels.
