The Casacelli Family Saga (4 Book Series)

From Book 1: When Niko Casacelli learned of his wife's affair, he had no choice but to end their marriage. Niko was not the kind of man to play second fiddle to anyone. He might have loved her once, but her deception put an end to that, and he was glad to see her go. So, when Bianca Scott-Lee arrives on his doorstep begging him to pretend to be married for one last Christmas, he wants to tell her to go to hell. Only he doesn't. Their marriage was a mistake, but Niko discovers he's willing to go to any lengths to get her back in his bed, even if it is just for the holidays.
