An Oath Taken

2014

A man of honor. A woman of spirit. As the new castellan, Sir Nicholas Beringar has the daunting task of rebuilding Ravenmoor Castle on the Scottish border and gaining the trust of the locals—one of whom wastes no time in trying to rob him. Instead of punishing the boy, Nicholas decides to make him his squire. Little does he know the thieving young lad is really…a lady. Lady Elizabet Armstrong had donned a disguise in an attempt to free her brother from Ravenmoor’s dungeons. Although intimidated by the confident Englishman with his well-honed muscles and beguiling eyes, she cannot refuse his offer. Nicholas senses that his new squire is not what he seems. His gentle attempts to break through the boy’s defenses leave Elizabet powerless to stem the desire that engulfs her. And when the truth is exposed, she’ll have to trust in Nicholas’s honor to help her people—and to surrender to his touch…

An Oath Broken

2015

Lady Sarra Bellacote would sooner marry a boar than a countryman of the bloodthirsty brutes who killed her parents. And yet, despite—or perhaps because of—her valuable holdings, she is being dragged to Scotland to be wed against her will. To complicate the desperate situation, the knight hired to do the dragging is dark, wild, irresistible. And he, too, is intolerably Scottish. Giric Armstrong, Earl of Terrick, takes no pleasure in escorting a feisty English lass to her betrothed. But he needs the coin to rebuild his castle, and his tenants need to eat. Yet the trip will not be the simple matter he imagined. For Lady Sarra isn’t the only one determined to see her engagement fail. Men with darker motives want to stop the wedding—even if they must kill the bride in the process. Now, in close quarters with this beautiful English heiress, Terrick must fight his mounting desire, and somehow keep Sarra alive long enough to lose her forever to another man…

An Oath Sworn

2015

Bound by honor to save a country they love… The bastard daughter of the French king, Marie Alesia Serouge has just one chance at freedom when she escapes her captor in the Scottish highlands. A mere pawn in a scheme to destroy relations between France and Scotland, Marie must reach her father and reveal the Englishmen’s treacherous plot. But she can’t abandon the wounded warrior she stumbles upon—and she can’t deny that his fierce masculinity, Scottish or not, stirs something wild inside her. Colyne MacKerran is on a mission for his king, and he’s well aware that spies are lying in wait for him everywhere. Wounded en route, he escapes his attackers and is aided by an alluring Frenchwoman…whose explanation for her presence in the Highlands rings false. Even if she saved his life, he cannot trust her with his secrets. But he won’t leave her to the mercy of brigands, either—and as they race for the coast, he can’t help but wonder if her kiss is as passionate as she is. With nothing in common but their honor, Colyne and Marie face a dangerous journey to safety through the untamed Scottish landscape—and their own reckless hearts…
