The Sibling Effect: What the Bonds Among Brothers and Sisters Reveal About Us

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.

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 is equal parts science, psychology, sociology, and memoir. Based heavily on new and emerging research, The Sibling Effect examines birth order, twin studies, genetic encoding of behavioral traits, emotional disorders and their effects on-and effects from-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.

Jeffrey Kluger is a senior editor and writer at Time magazine. He is the coauthor of the bestseller Apollo 13 and the author of Simplexity, Splendid Solution,  Moon Hunters, and two novels for young adults. He lives in New York City with his wife and daughters.
