Katie Campbell is a little girl who believes in God, and doubts the existence of magic, while Jack Campbell, her older brother, believes in magic and doubts the existence of God. But when the children are thrust into another world that is ruled by wizards who are at war with the almighty, there is no doubt that both God and magic are very real. It is this conflict which brings them to the Nohr World and starts the children on an incredible journey to do the impossible, find and capture the white horse that will usher in Christ's return.
With a valiant angel to watch over her, and a merry band of trolls as her brave companions, Katie must travel through a world filled with ogres, goblins, and monsters she has never dreamt of, to find an animal she never knew existed; all to save her brother from an evil wizard who will surely destroy him if she does not deliver the horse of power and glory, the white horse known as Majesty.
