Well, 'The Catcher in the Rye' is often part of reading groups. It's a coming - of - age story that explores themes of alienation and growing up. '1984' is also very popular in this context. Its dystopian setting and themes of totalitarianism, surveillance, and the power of language make for really interesting discussions. And then there's 'Jane Eyre', a novel that combines elements of romance, mystery, and social commentary, which is great for a reading group.
