Highland Avenger by Julie Johnstone

Eight years ago, savage Scots invaded Eve Decres’s home, murdering her family and plunging her into a nightmare. As sole heir to a strategically located castle on the border between Scotland and England, Eve became a prize to be wedded and bedded, and she fled into hiding. She survived by clinging to two dreams: one day reclaiming her inheritance, and finding love to build a new family from the ashes of her loss. But on the verge of beginning her journey to make her dreams reality, she makes a fatal error that alerts her enemies to her whereabouts.

Now, Eve is catapulted into a world of feuding clans and warring kingdoms where she’s forced to make a choice that threatens to destroy her chance at freedom and shatter her heart. Amid treachery and violence, she soon discovers her only hope dwells in tying herself to Grant Fraser, a noble, fierce Highland warrior. Though passion smolders between them, Grant is bent on vengeance and sworn to a duty that would thwart her own plans.
