Greyson Chance: My Sister's Tour Mate

The way I see it is my sister got all the talent and I got all the medical problems. She has so much going for her and my life is going nowhere. That is, until my sister invites me to join her on her tour. Later I find out her tour mate is the one and only Greyson Chance! We start to hang out and we both really like each other. But we can't let my sister find out about our relationship because she might cancel the tour. In fear of jeopardizing the tour, Greyson and I have to sneak around.
