What this book is about
National Park Ranger Anna Pigeon is on vacation in Big Bend National Park — the remote, dramatic Texas wilderness along the Rio Grande — when she witnesses the aftermath of a brutal attack. A woman is found near the border, badly injured, and Anna is drawn into an investigation that involves illegal immigration, the violence of the borderlands, and the specific politics of the US-Mexico boundary that runs through the park. Nevada Barr's seventeenth Anna Pigeon novel is the most directly political of the series, engaging with border immigration and the human cost of crossing in ways that are specific to the Big Bend geography.
