Ceep on going is the theme and i can prove this because he keeps on moving from place to place.
What really affected me was when Magee lost his parents, then went to live with his uncle and aunt and then lost them and then lost grayson. I really know how it is to loose people you love.
maniac magee is an orphan who used to live with his aunt and uncel until they started fighting and then he ran away. Then he found a family and friends and they took him in.
