The Wallflower's Wicked Bargain: A High-Heat Enemies-to-Lovers Regency Romance (Hearts of History) by Drake Lyons

He ruined her reputation in an instant. She’ll unravel his sanity one day at a time. Eleanor Hayes has spent three agonizing seasons as London’s most forgettable wallflower… until a scandalous misunderstanding traps her in the arms of the city's most notorious rake. Forced into a hasty marriage to avoid total ruin, Eleanor expects a life of quiet misery. She certainly doesn't expect her furious new husband to spitefully exile them to a crumbling, isolated estate on the Cornish coast. Sebastian St. John, Viscount Vane, despises the ton and the marriage trap he’s fallen into. He intends to leave his unwanted, quiet bride in the country and forget her. But as a sweltering summer heatwave strips away their aristocratic manners, Sebastian realizes his wife is no shrinking violet. Beneath her prim exterior is a spine of steel, a wicked tongue, and a lush, generous body that is slowly driving him mad. What starts as a bitter war of words in the suffocating heat quickly ignites into an explosive, insatiable physical bond. But when the outside world threatens their isolated sanctuary, Sebastian must decide if he is willing to swallow his pride and surrender his cynical heart—or risk losing the only woman who has ever brought him to his knees.
