The Highlander's Secret Avenger

Drostan Macquarie, the fierce battle-hardened Highlander, was still a young lad when his father first warned him of the ancient curse on the Macquarie clan. Should any of our kin sire a bastard, the entire clan will be cursed to die out. Drostan vowed then to live his life alone, far from the reach of the curse. But on the eve of Beltane, a sizzling kiss with a mysterious lass ignites Drostan's blood...and threatens his vow.
Amelia MacLeod is on the run, desperate to escape her past, and an abusive family. But Wolf Isle isn't just a place to hide, it may be her only hope of redemption-if she can doom her clan's enemy, the Macquaries. Only, she imagined her enemy would be a hideous brute, not a big, brawny, and kind-hearted Highlander like Drostan.
Because now Amelia's discovered a way to destroy the Macquarie Clan for good-if she can bring herself to infiltrate the clan, seduce Drostan, and bring about the Macquarie curse. Of course, she hasn't accounted for the far-reaching consequences of her own dark past...or her traitorous desire for the Highlander she came to destroy.
