Drawing on dozens of intimate audio interviews with families from all across the country, award-winning psychologist and writer Andrew Solomon redefines what it means to be an "ideal family" in America today. Solomon observes that America, led in large part by the women's, civil rights, and gay rights movements, has undergone a radical social shift in the last few decades.

While three-quarters of American children lived in families with two (first-time) married, heterosexual parents in the 1960s, today less than half do. The conventional family, Solomon argues, has broken into a multitude of perfect families, including gay families, multiparent families, adoptive families, foster families, families built through assisted reproduction, single parent-headed families, and child-free families. Although the structure of family has changed, economic and legal structures lag behind and need to adapt to accommodate this explosive new reality.
