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.

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. As the city buckles under the beat of a thousand feet, Lisbet becomes caught in a dangerous web of deceit and clandestine passion.
