Song recommendation help?!?! Needed quickly!!?

For English, we have to do a book report on a book we read that has to do with the "Teen Problem" Genre. I read the book "The Face on the Milk Carton". I thought it was a good book. But anyways, for our book report we need to include a song along with a brochure we make. If you have read this book, and can think of a song that could tie in with this, that'd be great. But if you haven't, I'm looking for a song possibly about trying to find out who you are or finding your identity. Maybe some thing about family being confused could work. The books about the girl being kidnapped, if there're any songs and that, that could work too, or maybe one abut milk.... It has to be appropriate for cl, so no like non-understandlable death-metal please!!
