Speaking from a necromancer's point of view, I can assure you that if her body is rotting in the ground it would take nothing short of a miracle to bring her back exactly the way she was. I knew a man who tried to bring his wife back (he did NOT sell her down the river but instead lost her to cancer) and he got close. He got incredibly close. But, one day the death sickness that had been rotting in her spirit and mind since she died overtook her and she tried to kill him. This was the closest anyone has gotten to true necromancy and it only ended in more heartache. Anyone who is trying to bring back flesh, spirit and mind can usually pick two. You never get all three.
Ritual and salt sound like a religious thing to me. A God. Since I've slept with one, I can't say I'm all that convinced it'll work. And, even if it does through some divine light, God always has a way of taking his payment.
