Charting the development of an oral contraceptive during the 1950s and its effect on "the sexual revolution" of the '60s. It was enormous. Says Sylvia Clark, who grew up before the pill was available: "Women began to see themselves for the first time in all of history as economically self-sustaining."

Among Sanger's motivations: her own mother, who had 18 pregnancies (seven of them miscarriages) and died at 49.

"The Massie Affair" chronicles a 1931 Honolulu rape case involving a young white Navy wife that became even more serious when one of the acquitted Hawaiian defendants was later kidnapped and murdered.

It uncovers "cold, hard truths about America and the people who ruled it."
