Fleance is the new king of Scotland, but he is the ruler of a divided nation. Rebels who dispute his claim to the throne are raiding villages throughout the country, spreading uncertainty and terror. According to the new king's advisers he must marry a woman from a royal blood line to strengthen his position. It seems that Rachel, sister of Fleance's dead friend King Duncan will be the next Queen of Scotland, although Fleance cannot forget Rosie, his first love. But when Rachel is abducted, Fleance's position becomes even more dangerous and a bloody civil war seems inevitable. In Blood Lines the epic story that began with Banquo's Son continues. In a world of honour and betrayal a young king must learn to put duty before his own desires.
