What a Difference a Duke Makes (School for Dukes #1)

Edgar Rochester, Duke of Banksford, is one of the wealthiest, most powerful men in England, but when it comes to raising twins alone, he knows he needs help. The only problem is the children have terrorized half the governesses in London. Until the clever, bold, and far-too-enticing Miss Mari Perkins arrives. Mari knows how to wrap even the most rebellious children around her finger. But their demanding, wickedly handsome father? He won't be quite so easy to control. And there's something else she can't seem to command. Her heart. The foolish thing beats so wildly every time Edgar is near. As his employee, Mari is strictly off-limits. But what if she's the one breaking all his rules? In the game of governess versus duke, how can Edgar maintain his defenses when the only thing he wants to do is let the tempting beauty win?
