A Tale of Two Dukes by Emma Orchard

No one is more surprised than Viola, Duchess of Winterflood, when she receives an offer of marriage from a man she’s not seen in over a decade. An independent widow, close to thirty, with two rambunctious boys, Viola has no obvious reason to accept the new Lord Ventris’s proposal. And yet… within two weeks, Viola finds herself walking down the aisle towards a man she despises and has sworn she’ll never kiss. But kisses are all that’s off limits: nothing else.
Accustomed to living a secretive life on the outskirts of society, Richard Armstrong never expected to inherit a title, nor the significant property that comes with it. But now that he has, he’s determined to keep it within his bloodline, and for that he needs an heir. And so, he seeks out the striking widow of his cousin, the late Duke of Winterflood, and offers his hand.
