Members of the forum choose and read a new book every month together, and then discuss it. You can nominate a book to be book of the month using the book's page on Bookshelves. Simply click the link that says 'Nominate for book of the month' on the left side of the book's Bookshelves page near the social sharing buttons. Don't be scared to nominate, as you can change your nomination to a different book if you think of something better.
