Jack Frost has accomplished the one thing he never thought was possible. He grew tired of his tricks and pranks. It's been three years since the Battle of Pitch, the Guardians have been quietly in the background, helping to make children around the world happy. When each Guardian has a set job, but the youngest Guardian feels as if his presence is no longer necessary, he wonders if the fate the Man in Moon chose for him was right. Set with the mindset of making a true difference in the world, Jack Frost is thrown backwards in time, back before he died to save his sister. Only this time, he has a chance to choose whether or not he wants to become a Guardian. When he wakes up in his past, he is greeted by the Princess of Scotland, a girl he had believed to be a pretend fairytale back in the modern times. As the two teens grow closer, each must be the master of their own fates. But all actions have consequences, both on their ever quickening relationship, and on the world.
