In "The Dark Is Rising" by Susan Cooper, the narrative emphasizes the concept of individual choice and the possibility of redemption. It suggests that no matter how many decisions one has made leading away from the right path, there remains a final opportunity to alter course. Every individual possesses the power to seek forgiveness and redefine their journey. This idea instills hope, reminding readers that one can always choose to return to a positive direction.

The message is clear: it is never too late for a person to seek the light, symbolizing goodness and truth. By urging individuals to turn back and embrace this light, the book conveys a profound truth about human agency—each person has the capacity to change their fate and embrace a more virtuous path. The interplay of darkness and light serves as a central theme, illustrating that redemption is always within reach for those willing to change.
