This was a short story or novella I read back in the mid 80's probably. It was published in one of the Analog-type periodicals, but I don't remember which one.
The main thing I recall is that a man's wife is brought back to life via a process called rekindling. She's been rekindled. The problem is she's nothing like her former self - she's cruel or mean and wants nothing to do with the former husband. Rekindled people have no obligation to return to their previous lives.
It's all kind of vague, but I remember that I really enjoyed this story and haven't been able to remember its title for years. I can't find it anywhere online. Ring any bells for anyone?
