An Abundance of Katherines

Three distinct voices carry the book: Colin's verbose overthinking, Hassan's irreverent loyalty delivered through crude wit, and Lindsey's warm code-switching between small-town girl and sharp observer. A reader could identify untagged dialogue from any of the three.

Hassan is a genuine comedy engine — his rest-stop prayers, defaced hate-speech carvings, and frank commentary generate laughs every few pages. The humor ranges from situational absurdity to self-deprecating narration, landing more frequently than Harry Potter's seasoning humor but less relentlessly than dedicated comedy books.

Printz Honor-level craft: Green's prose balances intellectual playfulness with emotional precision, using footnotes as a genuine narrative device rather than a gimmick. The voice is confident, the humor structurally integrated rather than decorative, and key emotional moments arrive through understated prose rather than melodrama.

Green navigates complex emotional territory rarely addressed in YA: the shame of failed potential, the difference between being loved and feeling lovable, and the paradox of wanting to control the future out of fear rather than ambition. Colin's emotional blindspot — unable to see that people love him because he defines love as achievement — is sophisticated character psychology.

Unusually strong math integration: the Theorem involves graphing, functions, and predictive modeling — a math teacher and ELA teacher can genuinely co-plan units. Geography and economics connect through Gutshot's factory-town decline. Religious studies benefit from Hassan's authentic Muslim representation. The appendix by mathematician Daniel Biss adds genuine mathematical rigor.

Every major theme generates genuine debate: Can human relationships be modeled mathematically? Is wanting to be remembered selfish or universal? Does Colin grow or just redirect his obsession? Students can disagree meaningfully about whether Colin's epiphany is earned or convenient, and whether the Theorem's failure proves or disproves his worldview.
