Adjusting to her role as a new mother, the young Catherine LeVendeur is looking forward to life at home in Paris. But when her nobleman husband, Edgar, learns that two of his brothers have been murdered, her peace is shattered. Honour dictates that he must return to Scotland to avenge their deaths and, despite what awaits them in his war-torn homeland, Catherine and the baby accompany him.

Reaching Scotland, Catherine is shocked by Edgar's tyrannical father, and the cold secrecy of the rest of his family. As soon as Edgar is away from home, the family expel Catherine from their care, leaving her seeking refuge in a strange country ravaged by civil war. Searching desperately for her husband, she knows it is far more important to discover who despises Edgar's family so much that they would try to destroy its whole lineage - including her infant son.
