In "Good Bones," Margaret Atwood explores the concept of transformation through the metaphor of individuals encasing themselves in cocoons. These characters have a vision of emerging into a new existence, symbolized by their carved representations with wings. This imagery reflects their desire for change and evolution in their lives.

Despite their aspirations, Atwood notes that there is no evidence that these characters actually succeed in their metamorphosis. The idea remains an unfulfilled promise, suggesting a deeper commentary on the struggles of self-improvement and the often elusive nature of personal transformation.
