Laura Valiant is a successful art historian, running her own company. She and her husband, Doug, a Wall Street lawyer, share an idyllic marriage. But Laura’s trust in her husband is shaken when she discovers he has a secret life apart from her – a life which will rock their love. Clare Benson is Laura’s childhood friend. They’ve been together through thick and thin, good and bad. When Clare asks Laura the biggest favour and greatest honour of all – to be guardian to her teenage daughter, Natasha – Laura discovers her personal and professional lives become dramatically intertwined. But in true Valiant style, Laura rises to the challenges ahead and, eventually, succeeds in achieving the happiness and fulfilment she craves.
