In "Unsheltered," Barbara Kingsolver presents a powerful metaphor with the character known as the Bullhorn, symbolizing unstoppable change and destruction akin to natural disasters like earthquakes and floods. This figure represents a force that individuals cannot ignore, as it disrupts their lives and forces them to confront harsh realities. Rather than seeking solutions or hope, many remain entrenched in self-interest, clinging to material possessions even amidst chaos.

The narrative highlights the struggle between adaptation and denial, emphasizing a societal tendency to prioritize short-term gains over long-term survival. As characters grapple with their circumstances, Kingsolver urges readers to reflect on the broader implications of their choices and the necessity of seeking a path towards light, rather than being consumed by the wreckage around them.
