Books like Gently in the Highlands by Alan Hunter

Highland laird Cole McTiernay sets off on a mission to retrieve something from the very Englishmen Cole has spent his life hating. When he finds that the "something" is a wild hellion, he balks, determined to make the return to Scotland as hard on her as it was for him to set foot on English soil. But though English herself, Ellenor intrigues him with her fierce spirit, and Cole's heart, deeply locked away for so long, may be vulnerable at last.

KIRKUS REVIEW An 18th century gothic set mainly in Scotland where all the familiar elements appear and disappear with last week's barley in the broth. Elizabeth, raised in the American colonies, lands there to toil in the kitchen of Bowain Castle where her father had been a servant. But a fleeing Bonnie Prince Charlie and her American intended turn up; there are attempts on her life and some genealogical surprises along with something truly terrible in that old tower. Active enough for Johnston's sedentary readership.

"Ordinarily, Lady Fiona Ormiston wouldn't think of forming an alliance with an ungroomed, barbaric Highlander, despite the protection he offers. But now, by request of the king, Sir Adham MacFinlagh, a brazen stranger and outsider unlike anyone she has met before, is to be her husband. Torn from solitude and the comfort of her family to make a home with the rugged knight, Fiona surrenders to Adham's powerfully passionate--and shockingly tender--touch, only to discover her new husband's family ties may lie with an enemy of the king. A sense of duty may have brought Adham to the marriage bed, but it's his powerful feelings for his beautiful, willful wife that will be his undoing. Ultimately, the bold knight will have to decide: Does his allegiance lie with his blood ties to the man who hopes to bring down the king or with the bride who has stolen his heart?"--Page [4] of cover.
