Surrender to the Highlander / Lynsay Sands.

"Edith Drummond owes her life to Niels Buchanan and his brothers. Waking after an illness to a castle overrun by rugged Highlanders is disconcerting, but so is learning that she's slowly being poisoned. Niels insists on staying by her side, and Edith soon discovers that even more dangerous is her wild attraction to the fierce warrior. Niels has never met a more courageous - or enticing - woman than Lady Edith. The idea of such a bonny lass being forced to enter a nunnery is more than any red-blooded Scotsman could bear. He'll gladly marry her himself. But while sweeping her off her feet is easy, it'll take all his skill to defeat her family's relentless enemies and convince her to surrender to his sweet embrace."--Back cover.
