Lady Fiona Jardine, wed for over a year and very pregnant, has never known marital peace. Her cold, cruel husband Will has gone missing, and when last she saw him, they had argued, he had struck her - and she has no memory of what she did next - only that later she'd awoken alone in her bedchamber. She fears that in her rage and terror, she might somehow have killed Will. When her husband's cousin Sir Richard Seyton is summoned to search for Will, Fiona is moved by his warm, outgoing nature. A knight and warrior of great skill, Richard immediately is drawn to Fiona's brave manner and soon sees in her an equal measure of inner courage. Confessing to him that she fears having killed Will, she accepts his determination to help her. Pursuing together the mystery of Will's disappearance, they fall in love. Meanwhile, the English are reinforcing their garrison in the Scottish Borderlands, putting Richard, Fiona, and Scotland in peril....
