Kati Marton’s bestselling Hidden Power is an engrossing look at twelve presidential marriages–from Edith and Woodrow Wilson to Laura and George W. Bush–that have profoundly affected America’s history.

Marton uncovers the behind-the-scenes dynamics of the ultimate power couples, showing how first ladies have used their privileged access to the president to influence staffing, promote causes, and engage directly in policy-making. Edith Wilson secretly ran the country after Woodrow’s debilitating stroke. Eleanor Roosevelt was FDR’s moral compass. And Laura Bush, initially shy of any public role, has proven to be the emotional ballast for her husband. Through extensive research and interviews, Marton reveals the substantial–yet often overlooked–legacy of presidential wives, providing insight into the evolution of women’s roles in the twentieth century and vividly depicting the synergy of these unique political partnerships.
