Bookish friends

I am in a book club. Well, I have joined one, and our first get-together is scheduled for later this month. I'm really looking forward to it. I've never been in a book club before, and I don't know the ladies in this book club very well (or at all). Do you have any advice for me about how to make the most of the meetings, what to bring to the group, and how to approach each book as I read it?

These are the books we'll be reading first. The Fault in our Stars by John Green, The Secret Keeper by Kate Morton, Casual Vacancy by JK Rowling, Oh Dear Silvia by Dawn French, The Line of Beauty by Alan Holinghurst, The Perks of Being a Wallflower by Stephen Chbosky, Jack of Diamonds by Bryce Courtenay, Floundering by Romy Ash, and Blog Inc by Joy Deangdeelert Cho.

Have you read any of them? What are your thoughts?
