which character proves to be the best friend to Ghost? Why?

I would say taht Lu Richardson becomes a good friend to Ghost. Lu is an albino black kid who runs track for the Defenders. Lu is very fast, and no one except Ghost can beat him. Lu strives to do his best to avoid having to deal with his appearance, constantly being humiliated that he is an albino. Early in the novel, Lu and Ghost are adversaries on the team, but come to befriend and respect one another by the end of the novel.
