Her highness and the highlander - Tracy Anne Warren

The second novel in an enchanting historical romance trilogy about three princesses brought together by friendship and fate. This is Princess Mercedes's story

While journeying home from Scotland, Princess Mercedes of Alden's coach is set upon and her personal guard killed. Barely escaping with her life, she seeks help at a nearby inn. But with no money and looking little better than a beggar, the townsfolk think her claims of being a princess to be nothing more than a far-fetched tale. Utterly forsaken, Mercedes wonders what is to become of her.

After years of soldiering, dispossessed Laird Daniel MacKinnon is finally coming home. At an inn he is confronted by a bedraggled young woman claiming to be of royal blood. Daniel doesn't believe her wild tale, but when she asks for his protection, he agrees to serve as her bodyguard-in turn she promises to reward him handsomely once they reach London. But Mercedes is still being pursued by ruthless hunters whose motives remain unclear.

As the danger increases, so does the desire she and Daniel feel for each other, until the two of them must face the greatest danger of all-falling in love.
