On Jdate, Anny meets and interviews Marv Rothstein, a handsome, seventy-five-year-old, emotionally unavailable diamond dealer. Anny is attracted to Marv, and they become involved in a torrid affair. But very soon, Anny discovers that the elusive Marv is a serial JDater prowling the singles sites for younger women, and that he still sees his much younger ex-wife. Anny decides to write a series of columns, modeled after Marv, about a man who can't face age, calling him Mr. X. As Anny's Mr. X columns gain recognition, she struggles with her conflict about Marv, her career hopes, relationships, and her coming of age.
