The House at Riverton

I freakin LOVE Kate Morton. If I could read nothing but her books from now on I'd probably be ok.
This book was just so lovely, and I had no idea what the "secret" was until the very very end. So so so so good. Read Kate Morton. Like now.

From the cover:

Grace Bradley went to work at Riverton House as a servant when she was just a girl, before the First World War. For years her life was inextricably tied up with the Hartford family, most particularly the two daughters, Hannah and Emmeline.
In the summer of 1924, at a glittering society party held at the House, a young poet shot himself. The only witnesses were Hannah and Emmeline, and only they -and Grace- know the truth.
The novel opens in 1999 when Grace is ninety-eight years old, living out her last days in a nursing home. She is visited by a young director who is making a film about the events of that summer in 1924. She takes Grace back to Riverton House and reawaknes her memories. Told in flashback, this is the story of Grace's youth during the last days of Edwardian aristocratic privilege shatter by war, of the vibrant 1920s and of the changes she witnessed as an entire way of life vanished forever.
