Even though Tash and Emily go to an all girls' school, they are into boys in a BIG WAY. They're also stepsisters and the best of friends. So when their mom and dad have to go Peru for work for a couple of months, leaving the girls in their own flat in Aunty Jay's house, they are seriously excited. Of course they've got to take their weird elder sister, Ali, hundreds of her Star Trek videos, and Fat Man the cat, but apart from that they are INDEPENDENT GIRLS. And when they find out that there's a dishy boy living in the flat downstairs, they just can't believe their luck.
