The Reading Group is about a group of women who meet regularly to read and discuss books. What starts out as a good idea born from a glass of wine and the need to socialize, turns into much more. Over the span of a year, Clare, Harriet, Nicole, Polly and Susan - five women of different ages, backgrounds and contrasting dilemmas - transform themselves through the shared community of a book group. Their reading group becomes a forum for each of the women's views, expressed initially by the book they're reading and increasingly openly as the bonds of friendship cement. As the months pass, these women's lives become more and more intertwined.
