The Decisions to Open a Relationship: To Three or not to Three: By James K. Beggan. Lanham: Lexington Books, 2023. 222 pages. $105 (HB) $45 (e-Book).

"The Decisions to Open a Relationship: To Three or not to Three" by James K. Beggan is a book that explores the complexities of opening a formerly closed relationship. Beggan draws from various disciplines such as psychology, economics, philosophy, and game theory to provide a comprehensive analysis of decision-making processes. While the book offers definitions and research on polyamory, it is primarily focused on theoretical perspectives rather than practical advice. The book's adversarial approach and lack of guidance may make it difficult for the average person considering opening their relationship to navigate. Additionally, the book only briefly mentions the issue of unicorn hunting and the potential emotional impacts on a third person involved in a polyamorous relationship. Overall, the book is more suited for academic research rather than providing practical insights for individuals exploring non-monogamous relationships. [Extracted from the article]
