Nineteen-year-old Jakob Novis and his fourteen-year-old sister, Lizzie, share a love of riddles and puzzles. As WWII gets closer and closer to Britain, the siblings find themselves amongst the greatest secrets of all – Britain’s codebreaking facility at Bletchley Park. As Jakob joins the country’s top minds to crack Nazi’s Enigma cipher, Lizzie transfers notes between departments in the park and tries to solve the mysterious disappearance of their mother in her off time.

While the Novis siblings work hard on their tasks, messages and codes begin to arrive under their doorstep. It doesn’t help that while they try to figure out if the messages are truly for them (and possibly from their mother), that there is an inspector lurking outside the gates of the park, watching Jakob and Lizzie’s every move. They must figure out a way to put their bickering aside and work together to decipher the clues if they want to uncover the answers to the puzzle.

As usual, I will pick up anything Ruta Sepetys touches and learn about a part of history I hadn’t known about before I read the book. This book is no exception as we take a deeper dive into the codebreakers Bletchley Park during WWII. I knew there were codebreakers during WWII, but what I didn’t realize is that they consisted of mathematicians, chess champions, and librarians (which, as a librarian, this absolutely makes sense why they were needed!).

Though this book is aimed at middle grade, I will say it felt like it would be more for upper middle grade / younger high school age. Lizzie is fourteen and Jakob is nineteen so their voices were a little older, but nothing major or graphic happened that would make the novel need to be young adult.

Even as an adult, when it came to the description of the codes’ breakthroughs or the ins and outs of the Enigma machines, I would get lost, but overall I just assumed the characters knew what they were talking about and trusted them.

Overall, I loved the twists and turns that kept the pages moving for me. I know I had a hard time as an adult solving the clues, so young readers who like spies and code cracking, are sure to love this too.
