Welcome to Gately Comprehensive, a secondary school where no two days are the same. It could be anything, from the swimming pool being filled with jelly, a stampede of zebra through the gymnasium, right up to an alien invasion.
As the put upon teaching staff it's your job to take care of these problems, while ensuring you still cover all your classes, keep up with the marking and avoiding being volunteered for any extra-curricular activities. And all sorted in time for a pint down the pub after school, of course.

Winterdene is one of the jewels in the crown of British private education – a prestigious school in a magnificent setting, with a towering academic reputation, a formidable old girls’ network and a hockey team that strikes fear into the hearts of all who face it. That’s what it said in the prospectus, and that’s why your parents sent you there.

What the prospectus didn’t mention was Annabel Anderson, the cruel, conceited bully of the Fifth Form. All through your first year she made your life a misery. All through your first year you dreamed of getting back at her. And now, as you start your second year, you’re going to get your chance. Because this year you have a new best friend, and your new best friend will know how to deal with Annabel Anderson.

Oh… and did I mention your new best friend is a MONSTER?!
