Shirin is an Iranian princess; Ingrid, a German-Canadian eccentric; and Vivien, a Cuban-Jewish New Yorker culinary phenom. The three are roommates at a Swiss boarding school, where they spend their summers learning more than French and European culture. As the girls’ paths cross and merge—summers together, school years separate—they navigate social and cultural differences and learn the confusing and conflicting legacies of their families’ pasts. In the spirit of The Sisterhood of the Traveling Pants, Shirin, Ingrid, and Vivien grow together even when they are apart, forming unbreakable bonds along the way.
