I'm just watching The Heart of Me which is the film of The Echoing Grove. Helen Bonham Carter and Paul Bettany are great in it - Ricky is being an absolute spineless knob at the moment, I can't remember from the book if he redeems himself later on!
I also love Elizabeth Jane Howard but I never seem to find anyone else (apart from my mum) who loves these authors. I especially love ones set around World War II - anyone got any suggestions of others I might enjoy?
