All over the country children go to stay with step-parents, stepbrothers and stepsisters at the weekends. It's just like an endless chain. A step-chain.
I'm Ryan and I'm not impressed. My stepbrother Joss is coming to live here. Mum thinks I should be fine about this, she thinks we're best mates. She's got it all wrong! He mocks me and tests me and makes my life a misery. But nobody listens or cares. I've got to face up to him before he gets us both in big trouble...
