This is the first time I've read this as an adult -- I reread it incessantly as a child. "Sally J. Freedman" may be the best shot Blume has at a book that will outlive her. She is perfectly convincing at expressing a child's innocent bafflement at the concept of human evil. The stories Sally invents in her effort to understand the Holocaust -- Hitler is alive and retired in Florida! -- are humorous without making light of the subject.
This novel may well become a children's classic. So why on earth does my library only have it in e-book and audible form?
