Madam President by William Hazelgrove

While on a trip to promote the League of Nations in 1919, President Woodrow Wilson had a debilitating stroke, which left him an invalid for the rest of his life. His second wife, Edith, in effect became the president in everything but name. She had little formal education and the two had been married just a few years. But she assumed more and more of his responsibilities, with a goal of protecting her husband and his legacy by any means necessary. Ironically, at the time, women in the United States did not yet have the right to vote.

It's a fascinating story that was completely news to me. And Edith Wilson was really a woman ahead of her time.
