Charms of a Witch — Marina Oliver

Lucy has been brought up with her cousins, and never knew her parents, or even who her father was. When she hears that her grandmother, living in a small village, is ill, she insists on going to care for her. At first all is well, but after the grandmother dies the villagers begin to treat Lucy with suspicion, claiming she is a witch. When Matthew Hopkins, the Witchfinder General, arrives, Lucy is in great danger until there is unexpected relief from the reclusive Squire and his heir.
