Wicked in His Arms by Stacy Reid

Tobias Walcott, the Earl of Blade, has learned it is best to exercise rigid control over his passions and emotions in all that he does. Uncaring that it makes him seem cool and aloof to most in the ton, he is content with his desire to only woo agreeable and demur females. Then unforeseen circumstances see him trapped in a closet at a house party with the last woman he would ever make his countess.

Lady Olivia Sherwood is everything he should not desire in a female—unconventional, too decisive, and utterly without decorum. But passion ignites between them and they are discovered. Honor demands they wed, and while Tobias finds himself unwillingly drawn to the bewitching beauty, he must do everything not to tempt the passion that burns in him for her, lest it leads to disastrous consequences.
