Rate this book
A wartime secret. A journey to uncover the truth.

Claire has always had a special bond with her aunt Margaret, but she’s astonished when Margaret suddenly begins talking about a friend called Agnes, who Margaret met working as a WAAF in World War 2 – a past Claire had no idea about. Margaret and Agnes were best friends until Agnes started acting strangely, becoming secretive and distant. Then one morning, Agnes vanished and never returned home, leaving Margaret distraught.

Claire promises to delve back into the past and help discover what happened to Agnes. But Margaret’s memory is rapidly deteriorating, and apart from an old photograph of the two women, Agnes seems to have disappeared into thin air. Can Claire uncover Agnes’ story before it’s too late?

Oh wow! What a wonderfully emotional and enthralling book. It's a dual timeline which I love.
Margaret and Agnes meet in the WAAF. Agnes is half French and has been living in France with her family but they come to England when Paris is invaded. She and Margaret hit it off straight away and progress to sharing a flat together. Then one day Agnes disappears and Margaret never sees her again. Claire is Margaret's niece and was brought up by her and now Margaret is in a nursing home. Claire is all she has left but Claire is having her own problems. Margaret's mind is going and Claire attempts to track down Agnes for her Aunt to put her mind at rest.
Agnes's story includes part of the war that I always liked reading about and don't often get as a storyline. The descriptions of the French countryside during WWII and present day were extremely well done. I loved this part of the story.
The book is quite heart wrenching at times and I really felt for Margaret.
I dropped a star because there were a few too many coincidences that were a bit unbelievable.
Hard to believe this is a debut novel. I'll certainly be looking out for more of this author's work.

Thanks to NetGalley and HQ Digital for an early copy of this book.

Margaret and Agnes become acquainted when both join the WAAPS. Margaret is English as they come, whilst French-born Agnes came to England as a child. Still, the differences between them don't matter and they become closer, eventually sharing a flat.

One morning, Agnes packs her bags and leaves their flat, never to return. As Margaret had no inkling of what Agnes had planned, she was left distraught. The next seventy years passed by but she never forgot her friend, wondering what ever became of her.

Margaret's niece Claire has always been close to her aunt, more like a daughter than a niece. Still, a time has passed since she last visited Aunt M. Her once vibrant aunt is approaching the end of her life and is becoming quite forgetful. Aunt M keeps mentioning an Agnes, intriguing Claire. Despite dealing with some major issues herself, Claire makes it her mission to discover what happened to someone who clearly was special to her aunt, hopefully bringing some peace of mind and closure before it's too late.

Corin Burnside has created a beautiful debut with Her Forgotten Promise. A dual time blended WWII/love story, it will have you turning the pages.

Set in both London and the French countryside in the past and present, it's a tale of bravery and resilience, long-lost love and new beginnings. I found the French setting to be more vibrant and exciting, despite the dreary atmosphere caused by the German Occupation. The township of St. Jean endured hardship and pain during this time and the community had to rely on others to survive. The country's stunning backdrop wasn't disturbed though, retaining its beauty in Claire's time.

I do want to touch on Agnes and Margaret's relationship. A few people have felt misled- whilst I do agree that a lesbian couple in the 1940s was scandalous, the love they found and fought for each other is something to be admired and praised, not to get angry about in the 2020s!

Loved, loved, LOVED Her Forgotten Promise so much!

I loved this historical fiction which took place during WwII. Two young women were serving in the Women’s Armed Services in London during WWII when they fell in love. Agnes ends up being recruited to join the Special Forces and is sent to France as a radio operator and code decipher. When she mysteriously leaves, she is not allowed to tell her partner Maggie. Seventy years later, Maggie ends up sharing her story with her niece who she helped raise. The niece, Claire decides to search for her aunt’s long lost love and what might have become of her. Wonderful dual timeline story.

Disappointed

The synopsis of this book led the reader to believe it was a story of WWII and it was. It was also a love story. A homosexual love story. I feel that I was misled, and would not have purchased the book if I had known. This is not the type of literature I enjoy. I believe the story line was purposely omitted to “bait and switch” the reader’s interest, and I feel deceived.

Her Forgotten Promise is the debut novel from author Corin Burnside. It is a beautiful story of love and loss which is as heartbreaking as it is heartwarming. Our story is told through a dual-timeline narrative, moving between 2014 and the 1940s, as Claire tries to uncover the mystery of where Agnes went once her aunt Margaret lost contact with her during the war.
To say that this is Corin Burnside’s debut work is truly amazing. She has a real gift for storytelling and her vivid descriptions made the rural French setting come alive on the page and had me fully immersed within the story. The narrative is perfectly paced, the writing flows effortlessly and the history was also clearly very well researched.
From the synopsis I was not expecting a beautiful sapphic romance to be at the centre of the story and I’m a big fan of LGBTQIA+ representation within historical fiction so this was a pleasant surprise. Although I will say that omitting Agnes and Margaret’s romance from the marketing of the book did feel like an example of ‘history will say they were… roommates’ meme! Their friends to lovers love story was so beautiful that I thought it was a shame it was not shouted about in the synopsis and marketing.
Her Forgotten Promise is full of strong female characters who were all beautifully written with lots of depth to them. Agnes was a fantastic character with admiral courage, strength and tenacity. Through her I think Corin Burnside perfectly portrayed the incredible courage of the female SOE agents operating within the German-occupied countries during the war. I also loved Margaret as a character and thought she was fantastically written as both a young woman and an elderly woman. I did find myself struggling initially to warm to Claire, confused as to why she’d neglected to visit an elderly woman who had played such an important role in her life, but this began to change as the novel progressed and I ended up really enjoying her chapters.
One of my only criticisms would be that there were too many coincidences driving the plot which made it feel unrealistic at times. I also felt that the plot point surrounding Claire’s ex-husband and his new partner unnecessarily took our focus away from Agnes and Margaret.
Overall, Her Forgotten Promise is a fantastic debut historical fiction novel from Corin Burnside which combines themes of love, loss and courage into a fast-paced story about SOE work in wartime France. It is a must-read for fans of historical fiction.

This was an incredible story of love, loyalty and humans' ability to reach beyond their limits. The further I got into the story, the more "unputadownable" it became. Highly recommend it.

I absolutely loved this book. If you love France, love stories about the war and love romance this is the book for you. It was filled with courageous characters both during the war and the present day and true love which was pure and beautiful. It was easy to read, with smooth transitions between the past and the present and was difficult to put down. The ending was absolutely perfect too and will bring a tear to your eye!

Her Forgotten Promise

A favorite book of mine. So much heart ache in this WW11 story. From England to France, the story shows how so many people fought the Nazis and how so many women joined the fight. This is the story of Agnes and Magee who found a love with each other like no other. However, the war did separate them. Will they ever find each other and be reunited when the war ends?

This book was one of the most beautiful that I have read. Every night I had my Kindle tuned into this moving, wonderful book. I was sad when it ended, last night, one would want it to go on forever. I felt that I was right there when the good and not so good experiences. The suffering of those poor people was just horrid and thank God that it finally stopped.

Hoping for more by Corin Burnside. A very exceptional writer.

The title of Corin Burnside's debut novel, Her Forgotten Promise, has a nostalgic sound which perfectly suits this tale of a friendship lost during the chaotic events of WW2. In 2014 Claire’s elderly aunt Margaret is approaching the end of her life. She is unwell and sometimes confused, but during her moments of clarity she reveals her sorrow over losing contact with a close friend in 1943. Margaret and Agnes were WAAF radio operators together in London until the French girl’s sudden and unexplained disappearance. Claire’s deep love for the charismatic old woman who brought her up is clear from the early chapters of the novel. It is no surprise when she takes a break from her own problems to carry out research and find out what became of Agnes.
Her Forgotten Promise is beautifully written in dual narration, with Claire in 2014 and Agnes in 1943 expressing their different perspectives. Methodical Claire is motivated by a wish to soothe her beloved aunt’s emotional distress, while passionate Agnes is caught up in the need to defeat the forces of evil at all costs. Both women experience the darker side of life, Claire through personal betrayal and Agnes by her involvement in the cruelty and suffering of war.
Armed with the dry details of Agnes’ war record, Claire travels to France, where she seeks memories of the young woman who was so important to her aunt. Burnside’s descriptions of the food, scenery and farming community of the Pyrenees show a great understanding of the place, while Claire uncovers long hidden secrets and discovers the astonishing truth about Agnes.
It was a joy to read a novel with so many strong female characters. I am not a fan of historical fiction or books in which food plays a significant part, but the combination of romance and adventure in Her Forgotten Promise kept me turning the pages. Thanks to NetGalley and Harper Collins for an advanced copy.

Many thanks to #NetGalley and publishers for an #ARC of #HerForgottenPromise.
Wow.
This book jumps between two storyline in present day and WWII. It alternates most chapters, and each chapter ending leaves you wanting more. I feel like I have lost a group of friends after finishing this book. Not a lighthearted read, but it still is a great storyline to devour.

Here's a brief review of "Her Forgotten Promise," with plans to provide a more detailed one later on my bookstagram

"Her Forgotten Promise" is the type of book that lingers with you, evoking a lasting sense of melancholy long after you've turned its pages. It's akin to the emotions stirred when watching historical war films – a sentiment difficult to articulate, but one filled with gratitude for having not experienced such hardship personally. It's also accompanied by a profound sympathy for those who did endure it and a simmering anger toward those responsible for their suffering.

This book, in particular, felt like a cinematic experience. I found myself utterly engrossed in the characters' journeys, yearning to uncover the truth behind their experiences. My immersion in their stories ran so deep that I couldn't help but feel a genuine ache for them, even shedding a few tears along the way. Be sure to have some tissues on hand when you dive into this book; it will take me quite a while to move past the emotional impact it has left on me.

With thanks to NetGalley and HQ for letting me have an advance copy of this book for an honest review.

Well what can I say. I love books set during WW2. I always say I was born in the wrong time. The story tells of two friends, one of whom finds her ability to use her operator skills to an advantage to assist others during this timeline.

Without plot spoiling, the story is told from the point of view during the war and from the modern day as the niece of one the friends tries to discover what happened to them.

I found this a really easy read and wanted to keep turning the page to find out how the story developed and where the characters all fitted in. The description of the secret work undertaken was a well written and researched piece of work, so different to that of the land girls that are usually found in books of this era but equally just as valuable.

A twist in the tale, but nevertheless a really good, enjoyable read.

Thank you to NetGalley for the opportunity to read and review this book. This was an interesting World War II novel about what women did in England during the war involving being code interpreters and operators. The book involved a dual timeline, during the war which involved the story of Agnes and Maggie, and the 1990’s which involved an elderly Maggie and her niece Claire who is her next of kin and who Maggie raised as a teenager. The story focuses on Claire trying to find information about Agnes who lost contact with Maggie during the war and who never received any information about what happened to her. Maggie now elderly, suffering from some senility and other issues is more focused than ever about Agnes, so Claire steps in trying to help her aunt. The story was good, good characters, it was an interesting, emotional read. This was a good historical fiction story.

Thank you to @hqstories for allowing me to be a part of the #blogtour for this title. I love historical fiction so I felt that it was a given for me that I’d enjoy it, but I absolutely loved it! The book flits back and forth between time periods and character’s perspectives, giving the reader a real insight to the entire story. This is a beautiful romance, a heartbreaking look into life on the front and at home, a tragic loss and overall, a captivating story. I found myself trying to find time to keep reading throughout the day - I had to know more! An amazing debut novel and now an author I’ll look out for.

Entertaining by ok, loved it to the end.

I like happy books. Books with endings. Best is I feel good about while reading and at the end. Times are always tough during airtime. This shows that life is tolerable one day at a time. Nice to be shown young women during wartime.

Loved it

I started this book without expectations. The characters were so real I could picture them. Each one was different but the same. World war 2 was so bizarre and I was so interested in that history and the European experiences in the.time of Hitler the monster. It did not go into the gory details that most novels of the war told. I loved especially Agnes and Maggie. Claire, Danielle and the families and their friends were so real to me. I recommend it to anyone who likes adventure, history, romance gand patriotism.
