Boston, 1662. Mary Deerfield is twenty-four-years-old. Her skin is porcelain, her eyes delft blue, and in England she might have had many suitors. But here in The New World, amid this community of saints, Mary is the second wife of Thomas Deerfield, a man as cruel as he is powerful. When Thomas, prone to drunken rage, drives a three-tined fork into the back of Mary's hand, she resolves that she must divorce him to save her life. But in a world where every neighbor is watching for signs of the devil, Mary soon finds herself the object of suspicion and rumor. When tainted objects are discovered buried in Mary's garden, when a boy she has treated with herbs and simples dies, and when their servant girl runs screaming in fright from her home, Mary must fight not only to escape her marriage, but also the gallows.
