Cold hands, warm heart - (Jack Frost Reader Insert)

I don't know where I am. I don't know who I am. I don't know what I am. But somehow, I have managed to get tangled up in a battle between hope and fear, and the fate of every child in the world. Will the Guardians of Childhood succeed, and will I find what I was looking for... or even more?
