A marriage born of rivalry. A passion that conquers the border.

English knight Sir Adam Dayne has finally earned the ultimate reward from the earl who raised him. He is now the lord of Langford Castle. But his new title comes with a steep diplomatic price. To secure a fragile peace, he must accept a betrothal to the daughter of a Scottish Marcher warden. Adam is a warrior of duty and honor, fully prepared to accept his fate until he meets his tempestuous new bride.

Lady Cora Maxwell despises everything English, most of all the self-assured knight who has claimed her hand. Desperate to return to Scotland, Cora wages a war of outrageous defiance. She is determined to drive the new lord away before the vows are spoken.

But Adam is unlike any man she has encountered. He is a fierce protector who sees the genuine fear hiding behind her rebellion. Instead of breaking her spirit, he proposes a unique challenge. As they clash in the shadows of the keep, Cora is forced to face her deepest vulnerabilities and a burgeoning, undeniable desire for the very man she swore to hate.
