The Substitute (Vikaren)

The new 6th grade teacher has convinced the parents of her students that she is perfect for the job. When the door of her classroom closes she stops pretending. The fact that she is more evil than Snow White's stepmother crossed with an Ork does not really matter. There is something worse: she can read their minds. And there is something even worse than the worst: she does not seem human. And if she is not human, which is her mission on Earth? What is she planning to do by taking them to a school contest in France? And above all: how do you fight an alien?
