We rely on science to tell us everything from what to eat to when and how long to exercise, but what about relationships? Is there a scientific explanation for why some people seem to navigate relationships effortlessly, while others struggle?

According to psychiatrist and neuroscientist Dr. Amir Levine and Rachel Heller, the answer is a resounding yes.

In Attached, Levine and Heller reveal how an understanding of adult attachment-the most advanced relationship science in existence today-can help us find and sustain love. Pioneered by psychologist John Bowlby in the 1950s, the field of attachment posits that each of us behaves in relationships in one of three distinct ways:

• Anxious people are often preoccupied with their relationships and tend to worry about their partner’s ability to love them back
• Avoidant people equate intimacy with a loss of independence and constantly try to minimize closeness.
• Secure people feel comfortable with intimacy and are usually warm and loving.In this book Levine and Heller guide readers in determining what attachment style they and their mate (or potential mate) follow, offering a road map for building stronger, more fulfilling connections with the people they love.
