Every autumn, two and a half thousand pink-footed geese fly from Greenland to winter at Fala Flow, a protected peatbog south-east of Edinburgh. From this windy plateau, Karine Polwart surveys the surrounding landscape through history, song, birdlore and personal memoir. Ideas of sanctuary, maternity, goose skeins, Scottish football legend and medieval medicine all take flight, in this compelling combination of story and song.
