One of the most striking debuts in Scandinavian prose in recent years, ““One Hundred Years of Solitude” as Erlend Lou Could Have Written Them,” the novel “Muscat” by the young Norwegian writer Kristin Valla tells the romantic story of Clara Jorgensen, who is consumed by an insatiable craving for wanderings. On an island off the coast of Venezuela and at a provincial university in a high mountain town, she searches for her true love - and finds it.
