As the year 1349 approaches, the Black Death continues its devastating course across England. In Dorseteshire, the quarantined people of Develish --- guided by their beloved young mistress, Lady Anne --- question whether they are the only survivors. Thaddeus Thurkell, a freethinking, educated serf, and his companions quickly throw off the shackles of serfdom and set their minds to ensuring Develish’s future --- and freedom for its people. But what use is freedom that cannot be gained lawfully? When Lady Anne and Thaddeus conceive an audacious plan to secure her people’s independence, neither foresees the life-threatening struggle over power, money and religion that follows.

When the Black Death enters England in June 1348, no one knows what manner of sickness it is --- or how it spreads and kills so quickly. The Church cites God as the cause, and fear grips the people as they come to believe that the plague is a punishment for wickedness. But Lady Anne of Develish has her own ideas. She decides to bring her serfs inside the safety of the moat that surrounds her manor house, then refuses entry to anyone else, even her husband. Lady Anne makes an enemy of her daughter and her husband’s steward by doing so, but her resolve is strengthened by the support of her leading serfs...until food stocks run low. The nerves of all are tested by continued confinement and ignorance of what is happening in the world outside.

On the day Mr. and Mrs. Songoli’s young son fails to come home from school, 14-year-old Muna’s fortunes change for the better. Until then, her bedroom was a dank windowless cellar, her activities confined to cooking and cleaning. Now that Scotland Yard has swarmed the Songoli house to investigate the disappearance of the son, Muna is given a real bedroom and clothing, yet her world remains confined. Before long, though, it becomes clear that young Muna is far more clever --- and her plans more terrifying --- than the Songolis, or anyone else, can ever imagine.
