When Rachel Krantz met and fell for Adam, he told her that he was looking for a committed partnership--just one that did not include monogamy. Intrigued and more than a little nervous, Krantz decided to see whether their love could coexist with the freedom to date other people. Could they strike an exquisite balance between intimacy and independence, and find a way to feel passion for each other once the honeymoon phase ended?

Krantz documents her dive into polyamory, from Brooklyn sex parties to swinging and beyond, in her extraordinary debut memoir. As she attempts to write a new plot for her love story with Adam, she runs up against miscommunications, gaslighting, and ancient power dynamics, and seeks solid ground in a relationship where the rules are ever-shifting. An award-winning journalist, she interviewed scientists, psychologists, and people living and loving outside the mainstream as she searched to understand what polyamory would do to her heart, her mind, and her life.

With an unflinching eye and page-turning storytelling, Open is groundbreaking in both its documentarian approach to polyamory and its explicit subject matter. From debilitating anxiety spirals to heart-opening connections with the men and women she dates, Rachel puts her whole self on the line as she attempts to redefine what a relationship is--or could be.
