When Vonceil's older brother, Elber, comes home to their family's Oklahoma farm after serving on the front lines of World War I, things aren't what she expects. His experiences have changed him into a serious and responsible man who doesn't have time for Vonceil anymore. He even marries the girl he had left behind.
 
Then a mysterious and captivating woman shows up at the farm and confronts Elber for leaving her in France. When he refuses to leave his wife, she puts a curse on the family well, turning the entire town's water supply into saltwater. Who is this lady dressed all in white, what has she done to the farm, and what does Vonceil's old uncle Dell know about her?

To find out, Vonceil will have to strike out on her own and delve deep into the world of witchcraft, confronting dangerous relatives, shapeshifting animals, a capricious Sugar Witch, and the Lady in White herself—the foreboding Salt Witch. The journey will change Vonceil, but along the way she'll learn a lot about love and what it means to grow up.
