Coup de Grâce

In the early noughties, a time when sexual minorities were not quite so widely accepted in British schools, Eva Lawton is revealed to be gay after she has an affair with a female teacher. Consequently she falls victim to Queen Bee Grace Knox and her group, despite her defiant upholding of her identity.
However, when Eva seduces the Queen Bee herself, a girl more troubled than she ever could have imagined, she inadvertently finds the fabric of her life irredeemably stained forever.
