One of the most popular book clubs these days is the relatively new Reese's Book Club x Hello Sunshine. Witherspoon has been celebrating women's work in recent years and turning several books into popular movies. This club has a pick every month, which becomes an instant bestseller widely shared across Instagram (though there's not much discussion related to the book itself after it's announced).
Some recent reads include The Proposal by Jasmine Guillory, The Library Book by Susan Orlean, and Erotic Stories for Punjabi Widows by Balli Kaur Jaswal. Reese's Book Club is mostly an Instagram platform for book-lovers, with fun posts, memes, and giveaways curated by this famous book nerd. Elle Woods would be proud.
