Besides the natural physical changes that occur for Frankie in The Disreputable History of Frankie Landau-Banks, our heroine also undergoes some major transformations as she moves toward adulthood: falling in love for the first time, finding her identity, and even getting in trouble (and handling it like a boss). Frankie wastes no time in growing up and taking charge of her life. Even if it means losing that dreamy boyfriend she always wanted in order to stay true to herself.
Frankie enters the school year not really knowing who she is, but over the course of the novel, she grows into a young woman who is sure of her convictions.
Even though Matthew may like the way Frankie looks now that she is older, he can't really handle her intellectual maturity, and their relationship falls apart because of it.
