Charles Benoit's YA novel You is written in second person. According to the book jacket, Benoit is a former high school teacher and Edgar-award winning author of adult mysteries. I see the "former high school teacher" all over this book, which is unrelentingly grim, but worthwhile. The main character is a high school boy who has this to say about math:
It's your favorite subject. Which surprises you.
You like it because either you're right or you're wrong. Not like social studies and definitely not like English, where you always have to explain your answers and support your opinions. With math it's right or it's wrong and you're done with it. But even that's changing, with Ms. Ortman up there at the whiteboard saying how this year you'll be writing something she calls Mental Notes, which explain how you solved the problem and support your answer, saying that having the right answer isn't as important as explaining how you got it and bam, just like that, you hate math.
