For 20 years The Ethical Slut--widely known as the "Poly Bible"--has dispelled myths and showed curious readers how to maintain a successful polyamorous lifestyle through open communication, emotional honesty, and safer sex practices. The third edition of this timeless guide to the ethics of relationships, communication, and sex has been revised to include:

- Interviews with poly millennials (young people who have grown up without the prejudices their elders encountered regarding gender, orientation, sexuality, and relationships)
- Tributes to polyamory pioneers
- Tools for conflict resolution and instructions on how to improve interpersonal dynamics
- New sidebars on topics such as asexuality, sex workers, LGBTQ terminology, and ways polys can connect and thrive

The authors also include new content addressing nontraditional relationships beyond the polyamorous paradigm of "more than two" couples who don't live together, couples who don't have sex with each other, nonparallel arrangements, couples with widely divergent sex styles, power disparities, and cross-orientation relationships, while utilizing nonbinary gender language and new terms that have come into common usage since the last edition.
