Growing up in 1950s Detroit, Jo is the tomboy, the bookish rebel with a passion to make the world more fair; Bethie is the pretty, feminine good girl, a would-be star who enjoys the power her beauty confers and dreams of a traditional life. Jennifer Weiner tells a story of two sisters who, with their different dreams and different paths, offer answers to the question: How should a woman be in the world? Do we change or does the world change us?
