A fascinating look at what it's like to grow up in front of and beyond the cameras. --Eve PlumbFor nine seasons, Mary McDonough was part of one of the most beloved families in television history. Just ten years-old when she was cast as the pretty, wholesome middle child Erin, Mary grew up on the set of The Waltons, alternately embracing and rebelling against her good-girl onscreen persona. Now, as the first cast member to write about her experiences on the classic series, she candidly recounts the joys and challenges of growing up Walton--from her overnight transformation from a normal kid in a working class, Irish Catholic family, to a Hollywood child star, to the personal challenges that led her to take on a new role as an activist for women's body image issues. Touching, funny, sometimes heartbreaking, and always illuminating, Lessons from the Mountain is the story of everything Mary McDonough learned on her journey over--and beyond--that famous mountain. "For someone who started out as a sweet little girl afraid to speak up, it certainly is a pleasure to hear her shout from the top of the mountain now! --Alison Arngrim, New York Times bestselling author of Confessions of a Prairie Bitch"She's a radiant woman whose truth comes from within. . .if I had to pick one word that described Mary Beth, it would be resilience." --Earl Hamner, Creator of The Waltons"Mary is a whole lot more than Erin on The Waltons. This book shows how she's handled all the highs and lows with grace." -George Clooney Includes Never Before Published Bonus Chapter!
