Is there a science to love? In this groundbreaking book, psychiatrist and neuroscientist Amir Levine and psychologist Rachel S. F. Heller reveal how an understanding of attachment theory - 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 explains 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.

With fascinating psychological insight, quizzes and case studies, Dr Amir Levine and Rachel Heller help you understand the three attachment styles, identify your own and recognize the styles of others so that you can find compatible partners or improve your existing relationship.
