Sewn with hate
When describing this book to a friend, I summarized as the story of two women in Victorian England: Ruth, a seamstress who believes she can hurt and kill others through her sewing, and Dorothea, a member of the gentry who visits Ruth in prison, believing that phrenology (the study of the contours of the human skull to describe a person's personality) holds the clues to Ruth's innocence or guilt. It sounds a bit wacky, I'll admit, but the story is so much more complex than that.
