Doomsday Brotherhood - 1, 5.

Ronan Wolvesey is an incorrigible bachelor, eternally searching for a woman for one night to enjoy...and forget. However, Kari Keswick cannot be forgotten. He can't cope with his growing obsession with the pub owner. But his family was cursed a thousand years ago, which means that if he succumbs to the temptation to make Kari his mate, it could cost the girl her life. Despite the fact that Kari fell hopelessly in love with Ronan from the moment he first appeared at the door of her establishment, she refuses to become another trophy of his bed exploits. However, the man’s inexorable attraction forces the girl to surrender to his mercy, even knowing that he will subsequently leave her. After spending time together, incomparable to any of the previous nights of love, Ronan realizes that he longs to have this woman in his complete possession forever. And then it’s time to make a fateful choice: let Kari live her own safe life away from him, or believe that true love will sweep away all obstacles in its path.
