In 'Lost Children Archive,' a family's journey dovetails with the poignant narratives of immigrant children. Echoes of estrangement reverberate as a couple and their two kids road-trip to the historic Apacheria. Creatively interspersing texts, voices, and images, Luiselli captures the fissures in the family and society. Bearing witness to a crisis at the border, the novel is a meditation on memory, identity, and the unseen scars left by the ghosts of history.
