Until the fateful day that her daughter is injured at school, Jessica Maroni figures that life is okay. Sure, being married to a workaholic pro-bono lawyer and living in Surrey on pennies isn't ideal - particularly when the yummy mummies at school take every opportunity to point out the differences between their husbands' incomes and hers. With their Range Rovers, size 6 skinny jeans and waist-length hair extensions, they couldn't be more different to Jessica and her own more 'herbal' approach to life. But when eight-year-old Rachel suffers a life changing injury, and husband Ronald refuses to pay for a private surgeon, Jessica becomes intimately involved with the vacuous group from school, a decision that dramatically changes the course of the future for herself and her family.
