Short Synopsis
A senior writer at Time magazine explores what scientists and researchers are discovering about sibling bonds, the longest-lasting relationships we have in our lives.

Full Synopsis
Nobody affects us as deeply as our brothers and sisters—not parents, not children, not friends. From the time we—and they—are born, our siblings are our collaborators and co-conspirators, our role models and cautionary tales. They teach us how to resolve conflicts and how not to, how to conduct friendships and when to walk away. Our siblings are the only people we know who truly qualify as partners for life.

In this groundbreaking book, renowned science writer Jeffrey Kluger explores the complex world of siblings in a way that's equal parts science, psychology, sociology, and memoir. Based heavily on new and emerging research, The Sibling Effect examines birth order, ongoing twin studies, genetic encoding of behavioral traits, how emotional disorders can affect—and be affected by—sibling relationships, and much more.

With his signature insight and humor, Kluger takes big ideas about siblings and turns them into smart, accessible writing that will help anyone understand the importance of siblings in our lives.

"This book had a profound impact on me that I never could have anticipated. . . . It's a compelling and beautifully written story, interwoven with fascinating, cutting-edge research." ---David Sheff, author of Beautiful Boy

"Here [Kluger] expands on his research to show what our longest-lasting relationship means to us. Since we're always digging for personal insights, I'm betting this book will be very popular." ---Library Journal

"Narrator Pete Larkin's tone is fresh and open.…[His] upbeat tone is particularly useful in some of the confessional sections of the book that recount less-than-happy moments." ---AudioFile
