All over the country children go to stay with step-parents, stepbrothers and stepsisters at the weekends.
It's just like and endless chain. A step-chain. "Girls Mean Trouble" is the second link in this step-chain.
I'm Ollie. My parents split up a while ago, and my brother and I live with Mum and Peter, my stepdad.
He's more laid back than my real dad, so going on holiday with him should be fun.
Except that Peter's daughters are coming along, too.
Girlsl I just know there'll be trouble...
