The dance tree / Kiran Millwood Hargrave.

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 as she is joined by hundreds of others, the authorities declare an emergency. Musicians will be brought in to play the Devil out of these women. Just beyond the city's limits, pregnant Lisbet lives with her mother-in-law and husband, tending the bees that are their livelihood. And then, as the dancing plague gathers momentum, Lisbet's sister-in-law Nethe returns from seven years' penance in the mountains for a crime no one will name. As the city buckles under the beat of a thousand feet, she finds herself thrust into a dangerous web of deceit and clandestine passion, but she is dancing to a dangerous tune.
