Peregrine: Singing In The Dawn

The story is about a man named Peregrine (like the falcon) who was banished from the Grand Temple because he was delving into the dark magic. His banishment ended, he travels the countryside seeking a particular man who will restore him to power. Instead, he finds Rescuer, age 13, and Abettor, age 10, and convinces them to join him in his travels. Everything goes well until they meet Abiel, a wise old, holy man -- the same man who had banished Peregrine. Both men try to convince the children that they would be safer with him, rather than with the other, and a tug-of-war for their allegiance ensues. Who will Rescuer and Abettor choose?
