'A brilliant ode to the necessity and complexity of female friendship.' HELEN CARR, THE SPECTATOR 'A tour through history proves female camaraderie is more than hashtags and girl power.' THE TIMES'Bad Friend fizzes with women navigating, testing and redefining this most powerful and complex bond.' KATHERINE ANGEL 'A wonderful, tender, joyous book. I urge you to read it.'
