“I have been standing on the side of life, watching it float by. I want to swim in the river. I want to feel the current,” writes Mamah Borthwick Cheney in her diary as she justifies, once again, her secret love affair with Frank Lloyd Wright. Four years earlier, in 1903, Mamah and her husband, Edwin, had hired Wright to design a new home for them. It was during this time that Mamah and the charismatic architect began to feel the sparks fly between them which caused them to embark on the love affair that would not only shock the Chicago society in which they lived but forever change their own lives.
