And the reward when good people die - her mother paused, swallowed, paused again - the reward when good people die is that they get to help make the people in their families who haven't been born yet. They pick out what kinds of traits they want the new people to have - they give them all the raw material of their souls, like their talents and their brains and their potential. Of course it's up to the new ones, once they're born, what they'll use and what they won't but that's what everyone who dies is doing, I think.
