Attachment theory is having a moment. It's the subject of much-shared articles and popular relationship guides. Why is this fifty-year-old theory, widely accepted in psychological circles, suddenly in vogue? Because people are discovering how powerfully it sheds light on who we love - and how.

Fascinated by the subject, award-winning journalist and author Peter Lovenheim embarked on a journey to understand it from the inside out. Peter interviews researchers, professors, counselors, and other experts as well as individuals and couples with attachment stories that illuminate the theory's key concepts. The result is this engaging and revealing book, which is part journalism, part memoir, part psychological guide-and a fascinating read for anyone who wants to better understand the needs and dynamics that drive the complex relationships in their lives.

PETER LOVENHEIM is a journalist whose articles and essays have appeared in the New York Times, USA Today, New York magazine, and other publications. He teaches writing at Rochester Institute of Technology and is also the author of Portrait of a Burger as a Young Calf, a firsthand attempt to understand the food chain, and other books. He lives in Brighton, New York, a suburb of Rochester.
