Borders are a lot more complicated than mere lines on a map.

Sites of globalization, borders fade away to promote trade. Sites of migration, they sort through people, rejecting the undesirable ones. Frontlines of defense against epidemics, they sequester and separate. Borders are places that allow us to apprehend the world. And in the hyperconnected world that surrounds us, they seem far more complicated than a mere line on a map. Drawing on many different examples, this book inaugurates the debate.
Swinging between free flow and stoppage, today's borders provide an original prism for understanding the world we live in and the relationships between us.
