A Promise for the Baby (Harlequin Super Romance Series #1898)

He always does the right thing 

There's one exception to Karl Milek's rule—the Vegas weekend that leaves him with a night to remember, and a beautiful new wife he'd rather forget. Those divorce papers are put on hold, however, when Vivian shows up on his doorstep pregnant. 

Karl offers her shelter and everything else she needs until their baby is born. Yet soon he realizes that he could definitely get used to seeing Vivian in the mornings, sharing dinner with her at night…and inhaling her jasmine scent. But he doesn't think he can risk giving his wife the one thing she wants most—his love.
