Miller makes Circe live with her mistakes and presses her to bear the consequences of them. Circe is able to grow because of her many blunders and, throughout all her actions, she never fails to feel distinctly human.
Throughout the story, almost every single character tries to scramble up the ladder of power. Minor gods try to win the favor of greater gods, mortal men try to become heroes, but Circe rejects fame that stems from ego, fear, and violence.
Feared for her gift, she is banished to the island Aeaea; but rather than being a punishment, the independence and freedom Aeaea affords her allows Circe to grow into her own.
