Witch Child by Celia Rees

"I am Mary. I am a witch." So begins the diary of Mary Newbury. After watching her grandmother being tortured and hung as a witch, Mary is determined to escape the same fate. With the aid of others, she sets off for America along with others who are leaving England in search of a new home. The year is 1659 and Mary knows she must keep her secret to herself. But she is not alone. There are others like her in the new world. But she must be very careful not to be found out. Even her journal must be hidden so others won't know her secret. but as the witchcraft trials begin, the village turns on her, and Mary must escape.
