In Valeria Luiselli’s fiercely imaginative follow-up to the American Book Award-winning Tell Me How It Ends, an artist couple set out with their two children on a road trip from New York to Arizona in the heat of summer. As the family travels west, the bonds between them begin to fray: a fracture is growing between the parents, one the children can almost feel beneath their feet. Through ephemera such as songs, maps and a Polaroid camera, the children try to make sense of both their family’s crisis and the larger one engulfing the news: the stories of thousands of kids trying to cross the southwestern border into the United States but getting detained–or lost in the desert along the way.
