Children's ✦ Penny’s Take
The Codebreaker Kids Return
George Edward Stanley · 1989
58/100
👎 Skip It
The interactive codebreaking format is a clever hook for curious upper-elementary readers, and sports rivalry gives the mystery a light, accessible frame. But the book is thin in narrative depth, 35 years old, and barely documented in modern sources — hard to recommend confidently when stronger middle-grade puzzlers exist today.
