The Witch of Blackbird Pond by Elizabeth Speare

When her grandfather dies, Kit Tyler leaves the prosperous life she has known in Barbados to live with her aunt in Connecticut in 1687. Kit has been raised to be a free spirit and has a hard time understanding the closed minds and strict regulations of the Puritans. When Kit meets the Widow Tupper, a Quaker who is believed to be a witch, they become close friends and Kit visits her often. Kit is accused of also being a witch after helping the Widow Tupper escape from the angry townspeople. She is accused of works of the devil which have caused illness and death to fall on many children in the town. Banishment, hanging or branding is the usual punishment for one accused of witchcraft. Will anyone step forward to help her?
