She won't find much that isn't common knowledge already:

One day, the gods and giants would go to war. They would die, and their magic would return to the place from which it came. The last to stand would be the Queen of Frost, and it was given to her to go to the heart of the world and give her life to freeze the world, keeping it safe in ice as it healed. When it melted, everything would be reborn, and the survivors chosen by the world would go on to create new life.

She will find that there is simply no literature that suggests that altering this prophecy is possible.
