An exciting WWII novel with action and suspense on every page. This book by Deborah Hopkinson will draw you in from a secret notebook to air raid sirens. Challenging ciphers for you to solve. Can Bertie Bradshaw save the Allies in the big invasion (D-day) and catch a traitor? Or will he fail? Read "How I became a spy" to find out.

I love this book! It is a great read for any time!!!! With codes in every section for YOU to figure out this is amazing. The plot itself would be enough to keep me hooked though. I would recommend it to anyone who likes mysteries, spy stories or WWII stories.

I loved reading it and solving the codes! Would definitely recommend.

its very interesting and would definitly recommend

Sad at times but very hard to put down
