But what if the young child perished in infancy 17 years ago and there is, sadly, no daughter to return? A warrior improvises…and finds a beautiful imposter to bring back to his native land.
The beautiful Rose Gunther has decided to be neither impressed, nor scared by the arrogant Scotsman who whisks her away from her English convent. But try to resist her attraction to the powerful Leith she may, she can’t deny how utterly helpless she is in resisting his sensual touch…
