["Good-by My Shadow"] is an uncommonly subtle study of a girl emerging from adolescent self-concern to levelheaded appreciation of herself, her family and her friends. Its appeal is for those past 15 who relish the author's flashes of humor, care with words, regard for family relationships—and who remember their own growing pains. This seems to me one of the more adult of Mary Stolz's books. (p. 34)
