Who they are in the book
Spoiler-freeMary initially resents Vonnegut’s visit because she believes he will portray boys at war as impressive grown men, helping another generation imagine combat as exciting.
Vonnegut takes the criticism seriously and promises the book will not glorify war. Its subtitle, The Children’s Crusade, honors that promise.
