When an ethereal stranger climbed through Tobias's bedroom window in the middle of the night, the young man had no idea that she came to claim him for a vital mission. Her world, in the Sky Realms above earth, suffered from a dark enemy. That enemy lived on earth and also worked to enslave human minds. After visiting the Sky Realms, Tobias realises he has little choice but to help his new friend and her family. The future of the Sky Realms and earth depended upon it. In battle, he prays for the courage to do what is expected of him, not realising that a long-lost part of himself, caught in another time, could undermine the entire mission.
