A popular writer, traveling with her husband through Sicily, ends up in an old, half-ruined castle in the mountains. There she meets the estate’s mistress, Tosk, and is introduced to the astonishing society of widowed women living in the estate’s lands where they once worked alongside their husbands. The stories of their lives, Tosk’s love story and the last owner of the castle—Prince Leo, whose lineage traces back to the French House of Anjou, which once ruled the island in the Middle Ages—are tightly interwoven with the tale of modern Sicily: its architecture, holidays, and cuisine.
