Since she was a little girl, the wind has dictated every move Vianne Rocher has made, buffeting her from the small French village of Lansquenet-sous-Tannes to the crowded streets of Paris. Cloaked in a new identity, that of widow Yanne Charbonneau, she opens a chocolaterie on a small Montmartre street, determined to still the wind at last and keep her daughters, Anouk and baby Rosette, safe.

Her new home above the chocolate shop offers calm and quiet; no red sachets by the door; no sparks of magic fill the air. Conformity brings with it anonymity—and peace. There is even Thierry, the stolid businessman who wants to care for Yanne and the children. On the cusp of adolescence, an increasingly rebellious Anouk does not understand. But soon the weathervane turns . . . and into their lives blows the charming, enigmatic—and devious—Zozie de l'Alba. And everything begins to change.
