The book Attached by Amir Levine and Rachel Heller hopes to teach the reader about attachment in romantic relationships and ways in which to apply the concepts of attachment theory to make a significant difference in the reader's life. Attached not only thoroughly teaches the reader about attachment theory, it also introduces examples, interventions, and tools which make this resource much more applicable for the reader. However, the lens at which this book was written was primarily through a culturally universal perspective. It appears as though the authors believe their resource can be useful for “all walks of life”, however, the majority of the research they cited was based on heterosexual relationships. Out of the numerous examples used throughout this book, only one briefly mentions a same-sex couple. The lack of multi-culturally relevant examples and research used in this book makes it an inadequate resource for sexual minorities.
