From USA Today bestselling author Scarlett Scott comes a fiery marriage of convenience between a forthright wallflower and her former flame's forbidden older brother…

Stuart Gilden, the arrogant and cold Duke of Camden, is suffocating beneath a mountain of debt caused by his wastrel father and gambling brother. To make matters worse, he’s being blackmailed by a mysterious enemy who has threatened to destroy him. Enter Miss Rosamund Payne, London’s greatest heiress, who has the wealth Camden so desperately needs. There’s just one problem: she’s his scoundrel brother’s former fiancée.

For years, the unassuming Rosamund has been plagued by fortune hunters, but one hurt her more grievously than the rest. When that rogue’s brother comes to her with a shocking proposition, she’s cautiously intrigued. Soon, Rosamund finds herself exchanging venomous barbs and searing kisses with the insufferable duke, lured by the prospect of revenge and the undeniable heat smoldering between them.

With their marriage of convenience secured, Camden’s problems should be at an end. But in truth, they’ve just begun. Because his enemy has only grown bolder and more dangerous. And the once unwanted wife beneath his roof is proving a maddening temptation he can’t resist, no matter the cost.

Heat level: Scorching hot! Don't say you weren't warned.
