For beauty junkie and others - the book is terrific! Try to get it if you can!
It's been a while since I read it, so I'll do my best here:
Caroline's husband's body has been recovered. She is sitting on her bench and the station attendant has just been to talk to her. She falls asleep, and dreams. She looks up and sees a bright light coming through the tunnel. She sees her husband, as he looked when he left, coming towards her. She gets up to run to him, turns around and sees her "old" body on the bench. She looks at her legs and notices they are young again. He reaches her and takes her through the tunnel, telling her they will always be together. The reporter and (I think I remember in the book it's her son, not her grandson, and the reporter is older) decide to live in the house and keep the rose garden blooming!
Kind of like The Ghost and Mrs. Muir, if any of you remember that!
