"A seemingly normal detention in a seemingly normal modern-day comprehensive school. A teacher valiantly battles on with biology revision. She believes only education will set her pupils free.

Despite all her best efforts, too soon the tide of conflict is lapping at the school gates and, one by one, pupils and teacher are pulled under as their hopes and dreams float away from them." --Back cover.
