Celia Rees: Witch Child

Mary's grandmother is executed for witchcraft, and Mary is forced to leave her home to avoid the same fate. At first she flees to the English countryside, but when the atmosphere of superstition and suspicion becomes all consuming she leaves on a boat for America in the hope that she can start over and forget her past. But during the journey, she realises that the past is not so easy to escape.

This is a gripping story about people's superstitions and the preacher's fear to lose their sheep to the so-called witches. The storyline hinted at Salem, but it would have been nice had that been followed up more rigorously.
