The Duke of Scandal by Tessa Brookman

“You’ll pay for trapping me into marriage.”

Lady Harriet is in a predicament. After the death of her father, her cousin has taken it upon himself to control her every move. Until during a fateful ball, she finds herself pinned between a dark garden wall and the body of the Duke of Wrexham – a cold rake notorious for his lack of commitment…
Duke Edward is a cold-hearted man who knows what he wants in life: A high-class match for his sister, and a tame Duchess for himself. But the virginal Harriet is anything but. And she proves it the moment her fiery kiss turns into a bite, and she disappears before he has a chance to speak…
When Edward’s sister disappears on her wedding day, Harriet offers her help. And just when he thought his life couldn’t get any more convoluted, a gossip column arrives at his doorstep with a shocking revelation:
He is engaged to the innocent Harriet… Unbeknownst to even him.
