“Diana Cosby is superbly talented.” NYT Bestselling Author - Cathy Maxwell

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…

“Who is he?” Colyne MacKerran asked.

He far from understood the importance of the question he asked.  “What does it matter who it is or the reason his men are searching for me?”

Colyne shot her a wry grin.  “If I am going to risk my life escorting you, I need to know what I am up against.”

Hope stumbled through Lady Marie Alesia Serouge.  “You will escort me?  But—”

The Scot held up his hand, any trace of humor gone.  “To my friend’s home as I offered before.  Nay more.  Once you are in safe hands, I must go.  I have my own business to attend to.”

Colyne’s reaction to the knights who’d ridden by flickered in her mind.  Uneasy, she cleared her throat.  “You believed the men were after you?”

His expression grew shuttered.

Marie tensed.  Was this Scot a threat?  She didn’t want to believe she’d miscalculated to such a degree.  But if she was wrong . . .

Long seconds passed as he stared at her, his deep gaze assessing.  “Aye, they are.”
“Why?” she asked.

A grim smile touched his mouth.  “Well now, lass, I have my own reasons.  Ones I will nae be sharing.  And,” he paused, “you will have to trust me as well.”
