"A beautiful, fiercely honest, and nevertheless deeply empathetic look at those who police the border and the migrants who risk - and lose - their lives crossing it. In a time of often ill-informed or downright deceitful political rhetoric, this book is an invaluable corrective."--Phil Klay. For Francisco Cantu the border is in the blood: his mother, a park ranger and daughter of a Mexican immigrant, raised him in the scrublands of the Southwest. Haunted by the landscape of his youth, Cantu joins the Border Patrol. He and his partners are posted to remote regions crisscrossed by drug routes and smuggling corridors, where they learn to track other humans under blistering sun and through frigid nights. They haul in the dead and deliver to detention those they find alive. Cantu tries not to think where the stories go from there. Plagued by nightmares, he abandons the Patrol for civilian life. But when an immigrant friend travels to Mexico to visit his dying mother and does not return, Cantu discovers that the border has migrated with him, and now he must know the whole story. This book makes urgent and personal the violence our border wreaks on both sides of the line.
