In 1983, Livvie Bliss leaves western North Carolina for New York City, armed with a degree in English and a small cushion of cash from a favorite aunt. Her goal is to launch a career in publishing, but more important, to live openly as a lesbian. A rough start makes Livvie think she should give up and head home, but then a new friend helps her land a job at a literary agency run by the formidable Bea Winston.

Bea hopes Livvie's Southern charm and "boyish" good looks will help her bond with one of the agency's most illustrious clients—the cranky Modernist writer Clio Hartt, a closeted octogenarian lesbian of the Paris Lost Generation who has rarely left her Greenwich Village apartment in four decades. When Livvie becomes Clio's gofer and companion, the plan looks like it's working: The two connect around their shared Carolina heritage, and their rapport gives Clio support and inspiration to think about publishing again.

But something isn't quite right with Clio's writing. And as Livvie learns more about Clio's relationship with playwright Flora Haynes, uncomfortable parallels emerge between Livvie's own circle of friends and the drama-filled world of expatriate artists in the 1920s. In Clio's final days, the writer shares a secret that could upend Livvie's life—and the literary establishment.
