When Anne-Marie Slaughter accepted her dream job as the first female director of policy planning at the U.S. State Department in 2009, she was confident she could juggle the demands of her position in Washington, D.C., with the responsibilities of her family life in suburban New Jersey. Her husband and two young sons encouraged her to pursue the job; she had a tremendously supportive boss, Secretary of State Hillary Clinton; and she had been moving up on a high-profile career track since law school. But then life intervened. Parenting needs caused her to make a decision to leave the State Department and return to an academic career that gave her more time for her family. The reactions to her choice to leave Washington because of her kids led her to question the feminist narrative she grew up with. Her subsequent article for The Atlantic, "Why Women Still Can't Have It All," created a firestorm, sparked intense national debate, and became one of the most-read pieces in the magazine's history. Since that time, Anne-Marie Slaughter has pushed forward even further and broken free of her long-standing assumptions about work, life, and family. In the twenty-first century, the feminist movement has stalled, and though many solutions have been proposed for how women can continue to break the glass ceiling or rise above the "motherhood penalty," so far no solution has been able to unite all women. Now, Anne-Marie Slaughter returns with her vision of what true equality between men and women really means and how we can get there. Slaughter takes a hard look at our reflexive beliefs -- the "half-truths" we tell ourselves that are holding women back. Then she reveals the missing piece of the puzzle, a new focus that can reunite the women's movement and provide a common banner under which both men and women can advance and thrive.
