In London, the public relation Helen is fired from her position in a PR company. While returning home, she does not catch the train in the subway. But in another possibility of her life, she catches the train in the subway. The story shows two parallel lives of Helen: in one life, she stays with her boyfriend Gerry, and in the other life, she finds that Gerry cheats her with Lydia and falls in love with James Hammerton.

Explores Austen's adage that general incivility is at love's essence. Sylvia's husband dumps her for another woman, so Bernadette and Jocelyn organize a book club to distract her. They recruit Sylvia's daughter Allegra; Prudie, a young teacher whose marriage may be on the rocks; and Grigg, a sci-fi fan who joins out of attraction to Jocelyn. The six read and discuss one Austen novel per month. Jocelyn tries to interest Grigg in Sylvia; Allegra falls in love with a woman she meets skydiving; Prudie contemplates an affair with a student; Sylvia's ex keeps popping up. In the discussions, characters reveal themselves in their comments. By the end, are truths universally acknowledged?
