Effie is changing the world, one classroom at a time.

Dark forces are at work at Highworth Grange school: the student council has been taken over by a tyrannical villain with his own agenda. But Effie Kostas isn't about to stand by and watch democracy crumble!

She's leading the resistance - but politics can be a dirty game and Effie will need to keep her wits about her as she faces down the enemy. With the help of her brilliant band of misfit friends, a bad-tempered parrot, and a former nemesis, can Effie save the school she loves before it's too late?

• A joyful celebration of one girl's mission to change the world!
