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.

Review by LordOfTheReads

This was one of the first books I read from PJ Our Way, and it was soooo good. If you like mystery stories, you would love this book!
