"Lost Children Archive" by Valeria Luiselli is a novel that follows a family on a road trip from New York to Arizona. The parents are documentarians and are working on separate projects, while the children are preoccupied with their own interests. As they travel, the family becomes increasingly aware of the migrant crisis and the children's obsession with finding lost things takes on a new meaning. The novel explores themes of family, identity, and the power of storytelling.

Set in the American Southwest, the novel explores the lives of impoverished Native American families living on the edge of a white man's town. Through the lens of a young girl from the Papago (Tohono O'odham) tribe, the story delves into themes of cultural identity, resilience, and the struggle between traditional ways and the encroaching modern world. The narrative poignantly captures the challenges faced by the community as they navigate poverty, discrimination, and the complexities of adapting to a world that often seems to value material wealth over spiritual richness. The title reflects the optimism and the spirit of affirmation that the characters must embrace to find joy and meaning in their difficult circumstances.

The novel follows the story of Codi Noline, a woman who returns to her hometown of Grace, Arizona to help her aging father. As she reconnects with her community and navigates her complicated relationship with her sister Hallie, who has disappeared in Nicaragua, Codi grapples with feelings of displacement and a lack of identity. The story explores themes of memory, heritage, love, and environmental conservation as Codi learns to find her place in the world and protect the land she calls home.
