Aviva Grossman, an ambitious Congressional intern in Florida, makes the life-changing mistake of having an affair with her boss – who is beloved, admired, successful and very married – and blogging about it. When the affair comes to light, the Congressman doesn’t take the fall, but Aviva does, and her life is over before it hardly begins. She becomes a late-night talk show punchline; she is slut-shamed, labelled as fat and ugly and considered a blight on politics in general. How does one go on after this? In Aviva’s case, she changes her name and moves to a remote town in Maine. She starts over, tries to be smarter about her life, and to raise her daughter to be strong and confident. But when, at the urging of others, she decides to run for public office herself, that long-ago mistake trails her via the Internet like a scarlet A.
