The Billionaire's Marriage Bargain by Carole Mortimer
Kenzie is determined to walk away from Dominick Masters. He never loved her, and certainly had never wanted to cement their marriage with a child. But now she's in a fix, and must ask her ruthless estranged husband for a favour, knowing that Dominick will drive the hardest bargain he can. And it is hard: he demands she spend a weekend at his country mansion, and be totally at his bidding! Kenzie has no choice but to agree, but finds being alone with Dominick a delicious temptation...Though, as she and he are about to discover, stolen passion has its price - how will Dominick react when he hears Kenzie's important news?
