One of the most famous paintings in the world by Andrew Wyeth portrays a young, frail woman in a field looking towards a farmhouse. It's called "Christina's World", and if you've ever seen this painting and wondered "Who is this woman and what is she thinking," then the novel A Piece of the World by Christina Baker Kline will satiate your curiosity. It's a fictional historical memoir following the stubborn nature of Christina, the woman in the painting, and her romantic history with Wyeth. West
