Are You There God? It's Me, Margaret was written by Judy Blume in 1970. It is a "young adults" novel, aimed at early adolescent girls, about Margaret, a girl of that age who is exploring her desire for a cohesive religion. The protagonist also confronts other pre-teen issues, such as buying her first bra, having her first period, and liking boys.
Due to its relatively frank treatment of adolescent sexuality and religion, this book is one of the top 100 most frequently challenged books at libraries (i.e., books that have been requested to be banned), according to the American Library Association. It also shares this list with Lost literary references A Wrinkle in Time and The Outsiders.
This book was seen being read by Sawyer on the beach, demonstrating his indiscriminate desire for reading material. He disliked the book, calling it "predictable", with "not nearly enough sex". ("The Whole Truth")
