a measure of relatedness between two antigenic substances
I'm glad I read this book now rather than when I was younger. I don't think I would have fully appreciated the romance between Anne Elliott and Captain Wentworth if I didn't have the perspective on marriage that I have now. And I wouldn't have enjoyed it nearly as much. This is not a playful story like Emma or Pride and Prejudice; the heroine is much wiser and more deserving. This may be my new favorite Jane Austen.
