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.

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!

A wonderful read!
This novel drew me in from the very first page and kept me hooked until the end. The characters were vibrant and relatable, the writing was engaging, and the story had just the right balance of heart and humor. Highly recommend!
Many thanks to NetGalley, the author, and the publisher for my ARC. All opinions are my own.

Suzanne Fortin has written a stirring novel of the secrets during WWII. A book that will keep you reading all night.
I received this ARC from NetGalley in exchange for an honest review.

Wow! I took a break from my usual thriller reads and this blew me away. My first book by Suzanne Fortin and I will definitely be reading more by her.
Hana Philips is going about her daily life when she is suddenly recruited to Bletchley Park to codebreak and spy hunt. Hana is a strong, intelligent young woman who is so easy to like. You can't help but be drawn into her story, her personal and professional life.
The story is gripping from he off, suspenseful, with the right balance of history, drama and emotion. The book is clearly very well researched, and the characters have had lots of thought and detail go into them. All too often the forgotten heroes and heroines of war are overlooked, here the are shone a light on.
If you enjoy historical fiction and mystery then this is for you.
Thank you to NetGalley, Suzanne Fortin and Embla books for the ARC.

I woke up one morning and decided that I needed a break from crime novels, it was all getting a bit predictable.
What I got with The Codebreaker’s Daughter was a tense spy drama, set in the fabulous Bletchley Park with likeable characters and a romance triangle thrown in.
I loved the book, the words kept jumping of the page at me and I found that I was gobbling up the red herrings. All came to a well thought out conclusion. This was a real thrill of a read, crime fiction may have lost me for the long haul.
Thanks to Netgalley and Embla Books for providing me with an Advance Reader's Copy in exchange for an honest, unbiased review.

Secrets, sacrifice, and a war she never saw coming…
The Codebreaker’s Daughter is everything I love in a historical fiction novel—rich with atmosphere, tightly plotted, and full of emotional weight. Hana’s journey from teacher to codebreaker at Bletchley Park is inspiring and tense, especially as the layers of betrayal and secrecy start to peel back.
What sets this one apart is how deeply personal it feels. Her mission to root out a mole becomes a battle between loyalty, legacy, and truth. The tension is sharp, the writing beautifully immersive, and the emotional payoff? Powerful. This book shines with quiet courage and quiet devastation. I couldn’t put it down.

This book is utterly sensational! From the very first page, I was completely captivated. The story had such an emotional pull that I found myself staying up far too late, night after night, unable to put it down.
Hana's journey is deeply moving—I felt like I was experiencing every moment right alongside her. Her pain, resilience, and connection with Gregory were portrayed so vividly that it was impossible not to root for her every step of the way.
The writing is powerful, the characters are compelling, and the emotional depth is unforgettable. This is a truly amazing book, and I would highly recommend it to anyone looking for a gripping and heartfelt read.

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.
