Elinor Mackey has lived her life in perfect order: college, law school, successful corporate career, marriage. But suddenly her world is falling apart. In her late 30s, she's discovered that she and her podiatrist husband, Ted, can't have children. When Elinor withdraws from Ted into an interior world of heartbreak and anger, Ted begins an affair with Gina, the nutritionist at their gym - a young woman with an oddball son who adores Ted. Meanwhile, Elinor falls in love with the oak tree in her front yard, spreading out her sleeping bag to sleep under the stars.
