Armed with a sassy haircut, a sharp wit, and a personal list of rules for all life's exigencies, Grace Santiago is a fiercely loyal Senate staffer who has everything under control. At least until famous political pundit Ethan Castle walks back into her life. Grace hasn't forgotten their disastrous affair in law school, but she can't resist his bad boy charm. When Grace learns that Ethan has been hired as a political gunslinger for the other side, her loyalties—and her heart—are torn in two. Though their sexual chemistry can't be denied, they find themselves locked in political combat. Ethan believes that all is fair in love and war, but he won't throw the election—not even to win Grace's heart. So what can a good girl like Grace do, but learn to play dirty? Two candidates. One election. May the best man—or woman—win!
