From ancient Greek tragedies, to the latest Netflix series, cheating women are portrayed as dangerous and damaged. Why, in this age of female empowerment, do we continue to judge them so harshly? Martin takes us on a fascinating journey to reveal the unexpected evolutionary legacy and social realities that drive female faithlessness, while laying bare our motivations to contain women who step out. From recent data suggesting women may struggle more than men with sexual exclusivity, to Martin's assertion that female sexual autonomy is the ultimate metric of gender equality, this book will change the way you think about women and sex. -- adapted from jacket
