The River Running by

The British community of Portugal in the nineteen-thirties welcomes Ruth, the bride of wine-taster Bobby Teape, into a privileged and wealthy world of rolling hills, great rivers and endless vineyards.

In the post-war turbulence of Portugal under Salazar's fascist regime, the children of Ruth and Natalia inherit a future that is scarred by Bobby's secret from the past.
