Maestro

The main way Paul matures is in his perspective of Keller. He goes from disliking his strict and unorthodox teaching style and joking that Keller is a war criminal, to loving and idolizing his teacher and having a deep interest in and respect for Keller's past. Paul also undergoes a sexual maturity in the novel, experiencing the effects of puberty, having his first sexual exchanges, and developing a relationship with Rosie. Paul also grapples with moral conflicts in the novel, including when his intellectual and sexual interests come into conflict, and he must learn to navigate them as he moves from youth to adulthood.
