I loved Eligible (read it in a day!), enjoyed Romantic Comedy, and I've got a couple of her others on my wish list.Loved Rodham. In fact Curtis Sittenfeld is one of my fave authors. I can highly recommend her short stories collections and American Wife.
I'm wary of Rodham because I don't like Hilary Clinton at all which I think would unfairly prejudice my reading of it if that makes sense?
