These wonderful books were written by psychotherapist Jessica Fern. While reading them, I became convinced that they weren’t just valuable for people in non-monogamous relationships, but for all people and all relationship types – and that they absolutely deserved to exist in German, too.
I reached out to the author, and together with my partner, I had the privilege of translating the books from English into German.
“Polysecure,” the accompanying workbook, and a poster – along with other fantastic titles – are available from divana Verlag and everywhere books are sold. The book has already gone into its fourth edition, and the German translation of the follow-up “Polywise” will be published later this year.
📚 You can order the books directly from divana Verlag in German and from Thornapple Press in English.

In recent years, attachment theory has gained increasing relevance in public discourse. However, most discussions tend to focus on how to create and maintain secure monogamous relationships. But what about people who seek secure and fulfilling bonds with more than one partner?
This is where polyamorous psychotherapist Jessica Fern breaks new ground. She expands attachment theory into the realm of consensual non-monogamy, offering a fresh and inclusive perspective.
By integrating attachment theory and trauma work into one combined model, Fern deepens our understanding of how these emotional experiences shape our relationships. She explores how past relational experiences influence the way we form attachments today – and how those patterns continue to impact us.
Building on this foundation, Fern introduces six specific strategies to support the development of secure attachments in diverse relationships.
These strategies are valuable for people in monogamous as well as non-monogamous relationship structures.
The workbook on relationship work for polyamorous people is a comprehensive tool designed to support and strengthen relationships – both with oneself and with multiple partners. Like Jessica Fern’s groundbreaking book Polysecure, this accompanying workbook is divided into three parts, offering readers a structured and practical approach:
Part 1: Attachment Theory & Self-Reflection
Understand your personal attachment style and how it shapes your relational patterns.
Part 2: Consensual Non-Monogamy
Exercises to help navigate attachment insecurity in the context of multiple relationships.
Part 3: Building Attachment-Based Relationships with Multiple Partners
With a special focus on the relationship you have with yourself.
Polyamory calls for a unique kind of relationship work – and in this workbook, renowned psychotherapist Jessica Fern offers guidance through insightful, hands-on exercises that encourage reflection, clarity, and connection.
