When a contaminated bolt of cloth arrives in a remote Derbyshire village in 1666, the community must decide whether to flee or endure a self-imposed quarantine to prevent the spread of the bubonic plague. Anna Frith, an eighteen-year-old widow and housemaid, serves as the narrative lens through which the reader experiences the rapid collapse of social order and the rise of religious fanaticism. As the death toll mounts, Anna faces the loss of her loved ones and the erosion of her community's moral fabric while navigating a forbidden romantic entanglement. The narrative, presented in the first person, captures the tension between emerging scientific inquiry and the desperate reliance on superstition during a period of profound isolation.
