'Fiendishly addictive' GUARDIAN Your best friend isn't who you think she is. You've been friends since university, when you became the people you are today. You don't see each other enough but when you do it's as if you've never been apart. She's one of the family. You would trust her with your life, your children, your husband. And when your daughter is rushed to hospital, you're grateful that she's stepping in at home, looking after things. But your best friend isn't who you think she is. You're about to find out just how wrong you were. 'Deliciously dark and addictive. I defy anyone who starts it not to race through the pages until they reach the final, brilliant twist' Colette McBeth 'Utterly gripping, fast paced, and scarily believable' Lesley Pearse 'Daly writes convincingly of a warped mind, the cracks in family life and the small triggers that send events spiralling out of control' Daily Mail 'Gripping, intriguing and unputdownable. I loved it!' Katie Fforde 'Confident and well-written' Literary Review
