Erica and Laure meet on the steps of the Sacré-Coeur in Paris, 1978. Erica is a student, relishing her first summer abroad before beginning university at home in England. Laure is studying for her PhD at the Sorbonne, drinking and smoking far too much, and sleeping with a married woman. The moment the two women meet, the spark is undeniable, but their encounter turns into far more than a summer of love. It is the beginning of a relationship that will define their lives and every decision they have yet to make. Erica and Laure’s love story spans decades, marriage, children, secret trysts and the agonizing changes --- both personal and political --- that might mean they can be together after all. But when life brings them within touching distance again, will they be brave enough to seize a future together?

Strasbourg, 1518. In the midst of a blisteringly hot summer, a lone woman begins to dance in the city square. She dances for days without pause or rest, and when hundreds of other women join her, the men running the city declare a state of emergency and hire musicians to play the Devil out of the mob. Outside the city, pregnant Lisbet lives with her husband and mother-in-law, tending the bees that are the family’s livelihood. Though Lisbet is removed from the frenzy of the dancing plague afflicting the city’s women, her own quiet life is upended by the arrival of her sister-in-law. Nethe has been away for seven years, serving a penance in the mountains for a crime no one will name. It is a secret Lisbet is determined to uncover.

Finnmark, Norway, 1617. Twenty-year-old Maren Magnusdatter stands on the craggy coast, watching the skies break into a sudden and reckless storm. All 40 of the village’s men were at sea, including Maren’s father and brother, and all 40 are drowned in the otherworldly disaster. For the women left behind, survival means defying the strict rules of the island. But the foundation of this new feminine frontier begins to crack with the arrival of Absalom Cornet, a man sent from Scotland to root out alleged witchcraft. Cornet brings with him the threat of danger --- and a pretty, young Norwegian wife named Ursa. As Maren and Ursa are drawn to one another in ways that surprise them both, the island begins to close in on them, with Absalom's iron rule threatening Vardø's very existence.
