Through two decades Deborah and Toby raise their children, embark on teaching careers, and argue about politics, education, and their own lives. One day during a hike, they have an argument that cannot be resolved--and the two women take different, permanent paths--but it is ultimately the borrowed book that will bring them back together. With sensitivity and grace, Alice Mattison shows how books can rescue us from our deepest sorrows; how the events of the outside world play into our private lives; and how the bonds between women are enduring, mysterious, and laced with surprise.
