Genevieve Ralston, a former mistress skilled in pleasing men, finds herself abandoned and vowing to avoid them, until the brooding and sexy Simon Cooperstone, Viscount Kilburn, enters her life. Simon's mission is to retrieve a secret letter from Genevieve, and he intends to seduce her to achieve his goal. However, as Genevieve's sensual touch awakens his deepest desires, Simon finds his own heart unexpectedly captured, realizing he may be outmatched by her mastery of seduction.
