A woman of rare valor - at the wedding ceremony of her sister Sarah, Agnes MacKenzie leapt in the path of a speeding arrow, saving Edward Napier's life. For Agnes, it was a matter of instinct and training - all Scotland knew her fame as a bodyguard. Few knew the heartache that spurred her perilous course.

A man of science - and mystery. Despite the towering rage of her father, Lachian, duke of Ross, Edward Napier used his medical skills to tend Agnes's wounds. Owing her his life, the widower granted her request to accompany him and his children to Glasgow. But he had no intention of allowing this beautiful, foolhardy woman to search out his unknown assassin.
