The literature on polyamory has expanded significantly in the past decade, and there's now a reasonable range of books, podcasts, and online communities available. The quality is uneven, and what's useful depends partly on where you are in your CNM journey. Here's a guide to what tends to be genuinely worth the time.
Essential books
The Ethical Slut (Hardy and Easton), The closest thing to a foundational text in polyamory communities. First published in 1997 and updated since, it covers the philosophical framework of CNM alongside practical guidance on communication, jealousy, and relationship structures. Some sections are dated and it reflects the sex-positive subculture context of its origins, but the core material remains valuable. Best for: people new to CNM who want a broad introduction.
Polysecure (Jessica Fern), An application of attachment theory to polyamory, with substantial practical content on how to build secure attachment within non-monogamous relationships. Published in 2020, it's become the most-recommended contemporary CNM book. Best for: people who want to understand the psychological dimensions of their CNM experience, particularly those who notice patterns of anxious or avoidant behaviour.
Rewriting the Rules (Meg-John Barker), A relationship psychology book with broad application that addresses non-monogamy, gender, and sexuality as part of a wider questioning of relationship conventions. More conceptual than prescriptive. Best for: people who want to think through their relationship values rather than receive practical guidance.
More Than Two (Veaux and Rickert), A comprehensive polyamory manual covering most practical dimensions of CNM in significant depth. Note: one of the authors has since been publicly named in community discussions about relationship ethics. The content of the book is largely sound and still widely referenced; the author history is something readers should know. Best for: people who want detailed practical coverage of specific CNM situations.
Stepping Off the Relationship Escalator (Amy Gahran), The most thorough treatment of the relationship escalator concept and non-traditional relationship structures. Methodologically grounded in actual research with people in non-escalator relationships. Best for: people questioning conventional relationship structure who want their experience validated and contextualised.
Podcasts worth listening to
Multiamory, One of the longest-running and most thoughtful polyamory podcasts, covering topics from jealousy management to relationship structure to communication tools. Evidence-based where possible, nuanced in presentation. A good ongoing resource.
Normalizing Non-Monogamy, Interviews with real people in CNM configurations discussing their experiences. Useful for exposure to the range of ways non-monogamy is actually practised.
Relationship Anarchy Conversations, Focused on relationship anarchy as a philosophy and practice. Worth understanding even if you're not a relationship anarchist, for the critique of conventional relationship structures it offers.
Online communities
r/polyamory, Reddit's polyamory forum is large (over 300,000 members), active, and relatively supportive. Quality varies but there's a significant body of people with genuine CNM experience willing to share perspective. Good for specific questions and the recognition that your experience is not unique.
r/nonmonogamy, Broader scope than r/polyamory, covering the full range of CNM configurations. Sometimes more practical, sometimes more chaotic.
Local in-person communities (munches, social groups, discussion meetups) vary significantly by city but are worth finding if they exist near you. The quality of peer support from people who've been navigating CNM for years is harder to replicate in online contexts.
What to be cautious about
Some CNM content prioritises ideological purity over practical usefulness. Resources that moralize heavily about the "correct" way to do polyamory, or that treat any deviation from non-hierarchical ideals as evidence of inadequate personal development, tend to produce guilt rather than guidance.
Individual blogs and social media accounts can be useful but are also where some of the most simplistic CNM content lives. The distance between "I've been doing polyamory for three years and here's what I think" and evidence-based relationship guidance is significant.
The most useful CNM content tends to be characterised by acknowledgment of complexity and genuine disagreement within the community, rather than confident pronouncements about what people should do.
