A great story!

Review by Hudson

How I Became a Spy is a great story about WW11 in London. It is also a great book if you want to learn about WW11 and codes and ciphers. You should read this book if you liked the book The Bicycle Spy.

The WWII adventure book

Review by AdamA

How I Became a Spy is a great WWII book filled with adventure and secrets, stopping you at each chapter to solve a riddle. A great book that keeps you on your toes, making you want to skip through the book to know what happens next. Overall a incredible book.
