When her husband, renowned author Noel Anderton, cheats on her, Corinne Pallin's cut-glass life shatters. In Edinburgh, surrounded by family and business, she is overwhelmed by the urgent need to get away and assess her life. On the edge of Loch na Duroir, Corinne finds a remote hideaway and is distracted from her heartache by the people she meets there: The beautiful Kate, her stalwart husband Ross, and their enigmatic daughter Louisa. Their problems resonate with Corinne and she is inextricably drawn into their complex lives. Caught up in a tangle of emotions, Corinne sits enthralled by the loch and reviews the unfailing love of her own family only to detect flaws under the caring veneer, and realises her own failure to recognise them. As she struggles to come to terms with the unfolding truth, a tragedy at the loch has her emotions slipping further out of control. Corinne must make decisions about her life, and rebuilt her future, a future shaped by passions from the past which must be faced. However, recent emotions stirred up on the dark shores of Loch na Duroir are fresh and tumultuous and will not be so easily laid to rest.
