In the wake of the EU referendum, the United Kingdom's border with Ireland has gained greater significance: it is set to become the frontier with the European Union.

Over the past year, Garrett Carr has travelled this border, on foot and by canoe, to uncover a landscape with a troubled past and an uncertain future.

Across this thinly populated line, travelling down hidden pathways and among ancient monuments, Carr encounters a variety of characters who have made this liminal space their home.

He reveals the turbulent history of this landscape and changes the way we look at nationhood, land and power.

The book incorporates Carr's own maps and photographs.
