Ms Divine, Milly's new teacher, introduced her to the class and said that Milly was a "star pupil".

Most of the children staring back at Milly were smiling, except for three girls in the front row...Milly worked very hard to get into Magic School, but now, on her very first day, everything seems to be going wrong - her pen won't write, her tunic changes colour, her hair stands on end.

Three girls are playing magic tricks on Milly. How on earth is she going to get them to stop?
