Cyrus MacKenzie, a powerful Highland chief and newly titled Earl of Stornmor, is in search of the perfect bride. The young, naïve daughter of a marquess should do nicely, but she's not the one who has captured his attention.

Lady Elspeth Seton, Baroness Grey, is a widow with a secret past. She's also a cunning businesswoman who has fought for everything she has. When a mysterious enemy turns her own guards against her and attempts to steal every piece of property she owns, she's uncertain who to rely on. With his fearsome warlord reputation and battle-hardened scowl, Cyrus is the last man she wishes to seek help from, but he's the only one offering it. She wants no domineering Highland earl taking control of her life, but in order to protect her home and her businesses, she must learn to trust him.

More accustomed to laying siege to castles than charming the ladies, Cyrus has no patience for stubbornly secretive women like Elspeth. He's infamous for deadly glares that terrify lesser men, but he's impressed by Elspeth's strength, fortitude, and canniness, for she not only stands toe-to-toe with him but also stands beside him to confront the enemy.

How can one ginger-haired lady with intoxicating eyes the color of whisky besiege his stone-cold heart? Even though his mind tells him she's the absolute worst woman for him, in his heart, he knows he will risk life and limb to protect her from the brutal Lowland laird bent on destroying her.
