Kids say this book is both enjoyable and thought-provoking, making it a fun read for children around the ages of 9 to 11, but some reviewers express concerns over its themes of bullying, mean-spirited behavior, and inappropriate language, suggesting that parental guidance is necessary. While Harriet is seen as a relatable character, her actions—such as spying and writing hurtful notes—may not serve as the best example for young readers.

What's the Story?

Harriet's in trouble when her classmates read about themselves in her secret notebook. When they start a Spy Catchers' Club -- and guess who's not invited to join -- Harriet turns to her nanny for help. Kids might not like the idea of Harriet writing about them, but they'll certainly enjoy reading what she has to say about everybody in her world!

Is It Any Good?

Our review:
Parents say ( 7 ):
Kids say ( 12 ):

This book is honest in its portrayal of the desperation and loneliness Harriet feels -- first, when her nanny leaves her and, later, when her friends turn against her. Girls, in particular, will identify with Harriet's strong drive to be true to herself in this longtime children's favorite.

Best of all, while HARRIET THE SPY deals with tough problems, such as how to deal with peer rejection and how to carry on without a beloved friend, it also manages, thanks to author Louise Fitzhugh's keen sense of the ridiculous, to be cheerful and often hilarious. Readers may even be inspired to start keeping their own notebooks -- though they shouldn't be so zealous as she is.

  • If someone did happen to find your notebook and read it, would there be things in it that might hurt other people? How would you explain your actions?

  • What other girl detective stories have you read? Why do you think they're so popular?
