Nancy Horan's Loving Frank depicts a real-life clandestine affair between famed architect Frank Lloyd Wright and Mamah Borthwick Cheney, one half of a couple who hired him to design their Chicago home. The affair was real, but the details scarcely known, as Wright's fame and success utterly eclipsed this brief romance. In this novel, Mamah takes centre stage, narrating how she and Frank — both married — came to fall into an affair that would change both their lives forever.
