I thoroughly enjoyed reading this book set during World War II in Bletchley Park. The pace was just right, skipping along at a good rate. The characters were well developed and the plot interesting. I found this book a page turner and read it in just a few days.

🔐 Secrets. Betrayal. A race against time. At Bletchley Park, trust is the most dangerous gamble of all.

Gripping from the first page, The Codebreaker's Daughter plunges readers into the high-stakes world of wartime espionage—this time from a rarely explored angle: decoding Japanese military and diplomatic communications. This unique perspective offers a fresh, fascinating take on Bletchley Park that fans of WWII fiction won’t want to miss.

Hana Phillips is a village teacher with a gift for languages, suddenly recruited into Britain’s most secretive operation. Fluent in Japanese and equipped with a sharp mind, she’s assigned to track down a mole leaking critical intelligence. But as her personal life unravels—her father in a coma, her marriage strained, her brother missing in action—Hana must stay focused as lives hang in the balance. With danger lurking even among her closest colleagues, who can she trust?

The suspense kicks in immediately and doesn’t let up, and I found it genuinely hard to put down. Hana is a compelling heroine, and the focus on the Pacific war front brought a new depth to the Bletchley narrative. This is not just another WWII historical novel—it’s a smart, sharp, and emotionally charged story of courage, resilience, and hidden heroes.

If you enjoy wartime fiction that blends real historical detail with twisty espionage and strong female leads, you'll be hooked. The Codebreaker’s Daughter brings a new dimension to WWII historical fiction, and I highly recommend picking it up.

I loved this story! I have read quite a few Bletchley Park books and I really enjoy them, this one however was a bit different because it focused on the war with Japan and breaking their codes. There’s a mole in the team, how many people are going to get hurt before the traitor is caught? No one can be trusted! This was fast paced, a lot of action happened straight out of the gate and it kept me hooked right through to the end. Highly recommend it’s a great story that is interesting and engaging. This is my first read by Suzanne Fortin and it won’t be the last, very good book!

Thanks to Netgalley and Embla Books for this advance copy in return for my honest review. Publication date 15 July 25.

If I’m honest this was rather too slow for me. I’ve read better books on the same subject that were less romance and more action. Try Kate Quinn if you want more substance to your historical fiction.

This book is set in England at Bletchley Park during WWII revolving around codebreakers trying to intercept Japanese messages and de code them. But there is a mole among them. The suspense in this book starts from the first page and you don’t know who to trust. It was hard to put down. Thank you to net galley for an advanced readers copy.

Wow! The Codebreaker's Daughter took off like it was jet-fueled and was impossible to put down. This isn't one of those books that eases you into the story as you get to know the characters. The plot unfolds at a breakneck speed and never slows down.

Although I've read many books set in Bletchley Park, this one focused on a group of codebreakers who are rarely mentioned, the decoders of the Japanese military and diplomatic communications. Imagine the difficulty...how many Englishmen are fluent Japanese speakers and knowledgeable of the cultural nuances? On top of that, one must have that rare "codebreaker brain." Enter Hana Phillips, who is all of those things but only a village teacher until she must continue her father's work, on the hunt for a mole in the Japanese sector. Meanwhile, her father is in a coma, her marriage is failing, her brother is in a Luftwaffe POW camp, and an American officer is being billeted in her home! Thank goodness women are conditioned to multitask. I loved everything about this fascinating book and I highly recommend it.
