Social Issues

I will be using the book SKUD to answer the main question "Why has this social issue been presented in your novel?". The social issue that will be used is inequality. Inequality is shown in the book SKUD when Brad gets taken off his hockey teams first line and gets put on the fourth line because a girl comes to the team who is faster and better puck handler than him but he was on the first line for three years in a row. The purpose of this  inequality in the book is to prove to Brad that hockey isn't the only thing in his life that matters.
