Here's why:
* They create a safe haven: The Boatwrights, particularly August, provide Lily with a safe and loving home, offering her refuge from her abusive father and a sense of belonging. They represent a "nest" where she can heal and grow.
* They nurture and support: The Boatwrights act as surrogate mothers to Lily, nurturing her and guiding her through her emotional journey. They provide her with love, acceptance, and a sense of purpose.
* They are connected to nature: Their home, the honey farm, is a literal representation of a nest. Bees are known for their communal nature and ability to create intricate structures, reflecting the Boatwrights' dedication to their family and their community.
While other characters, like Rosaleen, also play important roles in Lily's life, the Boatwright sisters' central role as creators of a safe haven and their nurturing nature solidify them as the primary nest builders in the story.
