Katie Couric has been a co-anchor of NBC's "Today" show since 1991 and is also a contributing anchor for its newsmagazine, "Dateline." Widely recognized for her journalistic excellence, sparkling wit, and quick intelligence, she has received two Emmys and was named one of Glamour's Women of the Year. Part of the proceeds from this book will benefit colon cancer research and prevention efforts, a cause for which Couric has been a vocal supporter since her husband died of the disease in 1998.
