Kit Milcourt – impatient, quirky, idealistic and brilliant – has been a climber, diver in exotic waters and affluent young city banker. Now, because of his beloved Anna, he is a teacher. Glumly mediocre Sandmarsh High School, reeling under assaults from Inspectors and its own unpromising pupils, is hard put to contain his maverick ideas. Year Seven, on the other hand, love them. Only the soothing presence of Anna keeps the peace.
