Teen Queens by Cathy Hopkins (author) (UK edition)

Lia has everything - a glamorous home and family, good friends, great looks and brains - and she has remained kind and unpretentious in spite of it. However, when she pulls the school heart throb in a game of Truth, Dare, Kiss or Promise, she alienates ‘teen queen’ Kaylie who was after Jonno for herself. Kaylie and her friends start a campaign of bullying against her - the nasty, underhand kind where rumours are spread, threats sent, secrets exposed and confidence undermined. Soon Lia begins to question everything - who she really is, why these girls have got it in for her and who her real friends are !
