The boy with glass magnets in is hands.
Lives in a city full of steel. All the other locals spend their days climbing and scaling the walls with their functioning magnets leaving him behind down on the ground. He knows that there is a better place to be found. Searching the vacant streets while people climb the wall he wonders what it is like up so high and tall.
While the others climb he is left behind. Because we all know glass magnets will not help him go!
