Mom reads this book to/with her eight-year-old son, who completely misses the part about spying ruining Harriet's life and instead collects his own set of spy equipment he can wear on his belt and finds ways to break into neighbor's houses and leave ziplock bags full of water in the freezer (for making snow cones). Oh, and my dad created a spy-themed birthday party for me when I turned nine. I have the coolest parents. Anyway, I submit that this is a great book because it got me to do all that.
