In "The Lacuna" by Barbara Kingsolver, the book explores themes of isolation, belonging, and betrayal through the experiences of its protagonist. As characters face various challenges, the idea of loyalty comes into question, particularly in moments of crisis. The narrative emphasizes the harsh reality that when danger arises, individuals often prioritize their own survival over solidarity with others, leading to feelings of abandonment.

One significant quote highlights this notion: "if the shark comes, they will all escape, and leave you to be eaten." This metaphor underscores the instinctual nature of self-preservation, suggesting that in dire circumstances, people may turn against each other, revealing their true character and vulnerabilities. The author weaves these complex dynamics into the fabric of the story, ultimately providing profound commentary on human relationships and the societal positions we navigate.
