?The Ethical Slut is a classic, a book that helped launch the modern non-monogamy movement. Updating a book of such historical significance is no easy task, but The Ethical Slut, Third Edition succeeds beautifully. Where the original broke radical new ground, this edition is more nuanced, a book for a more complex age. In the third edition, we see the wide variety of forms ethical non-monogamy, and indeed human sexual relationships, can take. This new version brings a new focus on consent, talks about the many wonderful and varied ways ethical non-monogamy happens, and shows an appreciation for the vast range of human sexuality. This is The Ethical Slut for a new era, and cements the book?s place as one of the cornerstones of modern non-monogamous thought.?
?Franklin Veaux, More Than Two: A practical guide to ethical polyamory

?In the two decades since the first edition of The Ethical Slut has been published, polyamory has expanded into a practice that, if not outright mainstream, is at least much more widely accepted and understood. [?] The 20th anniversary edition of The Ethical Slut, has been significantly updated and expanded from its humble debut, including sections to poly pioneers, black poly activism and yes, shifting attitudes towards polyamory within a new generation. They acknowledge that millennials reading the book today will not have been raised in the same context that Hardy and Easton were ? before the sexual revolution, when saving oneself for marriage was considered the norm.?
?Anna Fitzpatrick, Rolling Stone
