Between the World Wars, the six Mitford sisters—each more beautiful, brilliant, and eccentric than the next—dominate the English political, literary, and social scenes. Though they've weathered scandals before, the family falls into disarray when Diana divorces her wealthy husband to marry a fascist leader and Unity follows her sister's lead all the way to Munich, inciting rumors that she's become Hitler's mistress.

In 1909, Clementine steps off a train with her new husband, Winston. An angry woman emerges from the crowd to attack, shoving him in the direction of an oncoming train. Just before he stumbles, Clementine grabs him by his suit jacket. This will not be the last time Clementine Churchill will save her husband. Lady Clementine is the ferocious story of the ambitious woman beside Winston Churchill, the story of a partner who did not flinch through the sweeping darkness of war, and who would not surrender either to expectations or to enemies.

Her beauty almost certainly saved her from the rising Nazi party and led to marriage with an Austrian arms dealer. Underestimated in everything else, she overheard the Third Reich's plans while at her husband's side, understanding more than anyone would guess. She devised a plan to flee in disguise from their castle, and the whirlwind escape landed her in Hollywood. She became Hedy Lamarr, screen star.

The daughter of formerly enslaved parents, Mary McLeod Bethune refuses to back down as white supremacists attempt to thwart her work. She marches on as an activist and an educator, and as her reputation grows she becomes a celebrity, revered by titans of business and recognized by U.S. Presidents. Eleanor Roosevelt herself is awestruck and eager to make her acquaintance.

Mitza Maric has always been a little different from other girls. Most 20-year-olds are wives by now, not studying physics at an elite Zurich university with only male students trying to outdo her clever calculations. But Mitza is smart enough to know that, for her, math is an easier path than marriage. And then fellow student Albert Einstein takes an interest in her, and the world turns sideways. Theirs becomes a partnership of the mind and of the heart, but there might not be room for more than one genius in a marriage.
