Harry Boyd, a hard-bitten refugee from failure in Toronto television, has returned to a small radio station in the Canadian North. There, in Yellowknife, in the summer of 1975, he falls in love with a voice on air, though the real woman, Dido Paris, is both a surprise and even more than he imagined. Dido and Harry are part of the cast of eccentric, utterly loveable characters, all transplants from elsewhere, who form an unlikely group at the station. Their loves and longings, their rivalries and entanglements, the stories of their pasts and what brought each of them to the North, form the centre.
