“A groundbreaking book that redefines relationships.” – John Gray, PhD, bestselling author of Men Are from Mars, Women Are from Venus

In Attached, psychiatrist and neuroscientist Amir Levine, along with psychologist Rachel S. F. Heller, explores the science behind love, offering a practical guide to building deeper, more fulfilling relationships.

Is love rooted in science? This revolutionary book delves into attachment theory—one of the most advanced relationship sciences—revealing how understanding our attachment style can help us find and maintain lasting love.

Originally developed by psychologist John Bowlby in the 1950s, attachment theory identifies three main relationship behaviors:

• Anxious individuals often worry about their partner’s love and commitment.

• Avoidant individuals fear losing independence and tend to push intimacy away.

• Secure individuals are comfortable with closeness and naturally express warmth and love.

Through insightful analysis, interactive quizzes, and real-life case studies, Attached helps readers identify their own attachment style, recognize patterns in others, and make more informed choices in love—whether seeking a compatible partner or strengthening an existing relationship.
