Sisterhood is one of the most complicated relationships a woman can have. Marcia Millman spent hundreds of hours interviewing sisters to examine how these complex bonds are formed and how they keep changing throughout life.

Millman talked to sisters who were always close and sisters who became friends later; she talked to sisters who shared their childhoods but developed painful rifts as adults. She found that even those who are at odds often feel deeply attached-perhaps because the sister bond is inseparable from a woman's connection to her mother. Ultimately, Millman shows that sisters have the power to transform their relationships, as long as they relate to the sister in the present, and not just to the sister of the past.

In The Perfect Sister we learn about our sisters, our families, and ourselves as the book offers us the key to understanding, appreciating, and enriching the lifelong and incomparable bond of sisterhood.
