What is the theme in A Spell for Chameleon by Piers Anthony?

A primary theme of A Spell for Chameleon is growth and maturity, as it is a coming-of-age story for Bink, as well as for Xanth. As the protagonist, Bink matures between his twenty-fourth and twenty-fifth year, while on a quest. Through the sometimes painful process he gains knowledge and strength, while losing a previously held sense of innocence. Bink begins with a need for the self-knowledge of his magical talent, which is a kind of who-I-am-in-relation-to-my-world question.
