In an alternate world where New England is overtaken by a strict and religious brotherhood, witches are being hunted down and killed, or at the very least, sent to the madhouse. Many innocent girls meet their doom as the Brothers search for the real threat to their rule.
The real threat that is sitting just outside of town.
Cate Cahill is insistent upon watching over her sisters. Confronted with a love triangle, a new governess, a meddling neighbor and an absentee father, she sees her tightly-wound world fraying away. After her mother, a witch, died, leaving Cate in charge at just 13, the girl has had to protect herself and her younger sisters (all witches) from the hands of the brothers.
