Real Simple Magazine has an option for those of us who want to have the literary joy ;) of belonging to a book club, but without the pressure, planning, or even leaving our houses!
Each month people vote online which book they want to read (there's 3 or 4 options posted and you just have to pick one). After the votes are in, the book is announced, and you get to reading. During the month you can go on Real Simple's website and submit comments about the book/comment on what others have said. Didn't finish the book within the month? You're not the only one! You can still go on after the month and post/comment. Sometimes I just use this club to find good books to read and I skip the book club all together ;)
