Possession - Heavy going at times, but ultimately rewarding and one of my favourite books
The Blind Assassin - Sublime! Loved it, definitely in my top 10 of all time best reads.
Love both of these. Blind Assassin is my second favourite Atwood after Alias Grace (which was shortlisted for the Booker in a very good year, same year as A Fine Balance and Every Man for Himself which is one of Beryl Bainbridge's finest IMHO).
Agree that Possession is wonderful, should really read more A. S. Byatt, The Children's Book was one of my favourites last year.
