The worst girl in the school - or the best? It's the end of the school year and Elizabeth's fate will soon be decided!

Elizabeth is furious when a girl new to the sixth form becomes head girl over the obvious choice, her friend Emma. The new head girl, Kerry, is a young actress, and Elizabeth is convinced that all the seniors have been swayed by her acting skills, both on screen and at school. She knows the real Kerry is a nasty piece of work - but how can she prove it? She's determined to try and starts a campaign to replace Kerry with Emma. But Kerry is cleverer than Elizabeth thinks, and somehow she just manages to make the Naughtiest Girl look like a troublemaker!

Elizabeth is overjoyed to be appointed monitor again, especially when the new head-boy and girl have such exciting ideas. But one of the second form boys is slowly turning all the other boys against her, starting with a nasty note in her desk and ending with a false tip-off about a midnight pillow fight in the boys' dormitory. Rather than report it, Elizabeth plans to investigate - and, with the help of some friends, unleash a surprise waterpistol attack on the boys. But Elizabeth has been set up, as she discovers when she runs straight into their form teacher and the head boy - mistakenly squirting them both with water. Now, Elizabeth is in trouble again - and she could lose her prized monitor's role. Can she find out who has a grudge against her - and why?
