In a Pacific Northwest hospital far from the Rummani family's ancestral home in Palestine, the heart of a stillborn baby begins to beat and her skin turns vibrantly, permanently cobalt blue. On the same day, the Rummanis' centuries-old soap factory in Nablus is destroyed in an air strike. The family matriarch and keeper of their lore, Aunt Nuha, believes that the blue girl embodies their sacred history, harkening back to a time when the Rummanis were among the wealthiest soap-makers and their blue soap was a symbol of a legendary love.
