Attached: The New Science of Adult Attachment

Amir Levine and Rachel Heller translated adult attachment theory into a manual explaining why you choose the partners you do, and it's assigned by 40% of couples therapists who also use #1 The Seven Principles for Making Marriage Work. The three attachment styles—anxious, avoidant, secure—are now widely referenced in dating apps, but the book's power lies in helping clients identify patterns across multiple relationships with 80% clarity, according to reader surveys. Therapists assign it because it offers a framework for understanding why you repeat the same mistakes, and it's cheaper than the typical rival workbook at $12.99. Once you see your style, you can't unsee it.
