Today's book: The Line Becomes a River by Francisco Cantú.

The southern border between Mexico and the U.S. can be a violent place. Yet isn't as easily defined as it seems.There are places where the border is permeable, invisible. The border is a construct, and the racialized rhetoric of The Border combined with two decades of militarization have wreaked havoc on the people and the land.

Cantú becomes a border patrol agent to understand the realities on the ground ... but the complicity he feels drives him away. Can he escape the border, or does that mirage move with him?

Host Lisa Schweitzer is joined by Juan De Lara, Jaime Lopez, and Aubrey Hicks for a far ranging discussion of borders, metaphors, and life in between.
