The Bubble Wrap Boy

All my life I've been tiny Charlie from the Chinese Chippie, whose only friend is Sinus, the kid who stares at walls.
But I believe that everyone's good at something.
I've just got to work out what my something is . . .
Charlie's found his secret talent: skateboarding. It's his one-way ticket to popularity. All he's got to do is practise, and nothing's going to stop him – not his clumsiness, not his overprotective mum, nothing.
Except Charlie isn't the only one in his family hiding a massive secret, and his next discovery will change everything.
How do you stay on the board when your world is turned upside down?
