Isobel Campbell is on a secret mission to find sanctuary for Scotland's most holy relic. She is determined to see it to safety, but every step she takes brings her closer to an uncertain future. When the fate of the relic is assured, she must decide her own course. A lonely path forward seems inevitable, but her protector, a mysterious crusader, makes her yearn for a life filled with his love.

Alexander MacKinnon returns home to Scotland to face his clan's dire prospects. Escorting a noblewoman to a nunnery delays his reckoning with the family he left behind and presents dangers he cannot face alone. Isobel, his beautiful charge, may prove to be the greatest danger of all, for the powerful connection between them could lead to their ruin. But this crusader's heart cannot deny what it wants, even if it means putting everything at risk.
