Sophia's secret - Susanna Kearsley

After three hundred years, Sophia's secret must be told When bestselling author Carrie McClelland visits the windswept ruins of Slains Castle, she is enchanted by the stark and beautiful Scottish landscape. The area is strangely familiar to her, but she puts aside her faint sense of unease to begin her new novel, using the castle as her setting and one of her ancestors, Sophia, as her heroine. Then Carrie realises her writing is taking on a life of its own and the lines between fact and fiction become increasingly blurred. As Sophia's memories draw Carrie more deeply into the intrigue of 1708, she discovers a captivating love story lost in time.
