Horse game from earlier?

I used to play a horse game on a laptop, it should have been about 10 years ago, I would like to play it again and I'm looking for it. Unfortunately, I do not remember the name, but about what you had to do there. And although my was a girl who came to a new school, I think that she is newly attracted. The first scenes are also in the school, then you have to talk to people and I think I'm looking for textbooks, but in the end something happens and you break into the school at night and have to find something and of course to fit that you will not get caught. Then all I can remember is liberating a horse that was probably kidnapped before. You have to escape with them. Unfortunately I did not come far.

Maybe someone has played it and knows which one I mean.
