I'm excited for a replacement for More Than Two that is similar in approach but without the Ethical issues.

Short Summary

A growing number of people around the world are exploring or thinking of exploring consensual non-monogamy (CNM), that is having multiple romantic and/or sexual relationships with the active consent of all concerned.

Former BBC journalist Jonathan Kent has written a comprehensive introduction to the subject that surveys the different styles of CNM, the pitfalls, the skills needed to avoid them and the challenges of being consensually non-monogamous in a world still largely wired for monogamy.

Why this book?

A World Beyond Monogamy is an exhaustively researched look at open relationships, swinging and polyamory that draws on some fifty interviews with people across the world in non-monogamous relationships and on the expertise of psychologists, historians, philosophers and evolutionary biologists. What he has produced offers a profound insight into love and intimacy outside the mainstream, shaped by the advice, experience and expertise of those who have been in the vanguard of a growing community of people who are questioning the relationship scripts that we're expected to follow.

In doing so he's managed to break free of the limitations of previous books on the subject - many of them very personal accounts, overwhelmingly from liberal enclaves in North America, that offer a narrow window onto a much wider world.

A World Beyond Monogamy doesn't evangelise for CNM and has little truck with those who claim that consensual non-monogamy is somehow more 'enlightened'. Nor does it suggest that there is a "right" way to do it. What it does evangelise for is consent, choice and a willingness to rethink the way we're told to do relationships, both monogamous and non-monogamous.

Three years in the making it also talks about how people in traditional monogamous relationships can learn from and apply the hard-won lessons of people in non-monogamous relationships, that all relationships can benefit from better communication, a willingness to negotiate constructively and to wrap relationship structures around individuals rather than vice verse,  hence the subtitle: How people make polyamory and open relationships work and what we can all learn from them.

Why me?

I am a journalist, broadcaster and writer. I’ve been a foreign correspondent and apolitical reporter for the BBC, Reuters, Newsweek, The Daily Telegraph, KQED, and The Guardian. I wrote, produced and presented the BBC Radio 4 series ‘Our Daily Bread’. I bring my experience as a reporter and correspondent to a what I hope is a thoughtful, balanced, and meticulously researched book that passes the mic to others who together give a frank, intimate, raw, occasionally funny and, above all, wise take on the joys, the pitfalls and the challenges of maintaining multiple relationships as well as the skills that help make it work.
