Told with warmth as well as rigor, an invaluable book that not only illuminates and interprets the science of friendship but will help you wisely navigate your present and future friendships.

"Timely, savvy, and judicious.... Awash in arresting insights with practical implications, many of them counter-intuitive.” —The Huffington Post

Just as the role of friends is expanding in our culture, Friendfluence explores their powerful and often under-appreciated influence on our personalities, habits, physical health, and even our chances of success in life. In this fascinating book, packed with the latest research findings, Carlin Flora traces friendship from its evolutionary roots to its starring role in childhood and adolescence to its subtle (and sometimes not-so-subtle) impact on adults—both positive and negative, online and offline.
