Hi and thanks for stopping by.

I took up writing about twenty years ago when I first came up with a plot for a book, and I haven't stopped since. When I’m not writing, I’m ferrying around 3 teenagers or working as a nurse. I’m also an all-year-round sea swimmer.
I write what I love to read, which is romance and thrillers.

My next release, out February, 2026, is The Resistance Knitting Club, a World War 2 historical novel set in Guernsey, the UK and France. I am currently working on my third WW2 novel.

If you like my writing please get in touch - my social media links are below (I’m rarely on Goodreads so it’s best not to drop me a message here). I also have a newsletter, which you can sign up to via my website.

My Thoughts /

First and foremost, a huge THANK YOU to NetGalley, Storm Publishing and author, Jenny O'Brien for providing me with a copy of this publication, which allows me to provide you with an unbiased review.

An accomplished and popular author, O'Brien has written everything from crime to children's books. However, this is her first attempt at writing a book inspired by true events.

This is a win-win. A win for each of us (me and you). Due to two unexpected rounds of eye surgery I haven't been able to get to this one until now. Let me tell you that it's a winner. A winner for me to have the privilege to read it through a NetGalley get – and it's a winner for you too, because due to the fact that I'm late in putting up my review, you can get this one TODAY!

I will honestly never tire of reading stories such as this. This WWII historical fictional story was inspired by true events and is the remarkable story of one extraordinary woman's courage and kindness in the face of (unjust) adversity.

In a nutshell: Teacher, turned nurse, Evelyn Nightingale, used her position at the hospital where she worked to save patients from the Nazis in occupied Guernsey.

30 June 1940: Nazi occupation of the Channel Islands begins. The Nazis occupied four islands – Jersey, Guernsey, Alderney and Sark. Hitler believed the Channel Islands to be a 'stepping stone' from which to invade Britain. The Islands were also a useful propaganda tool – to show that the Nazis now occupied British land. Life under German occupation in Guernsey was drastically changed. Daily life involved restrictions on freedom, a ban on radios and other entertainment, and the forced use of German currency and continental time. Conditions worsened over time, leading to shortages of essential items, food scarcity, and a rise in crime. The Allied invasion of Normandy in 1944 further restricted supplies and worsened living conditions, with starvation looming for both islanders and occupiers.

This reader has read many novels set during WWII and many more from the perspective of nursing staff, but the occupation of the Channel Islands is not something that I've read before; but the stories retold by the people who lived there are no less harrowing – possibly more so.

O'Brien has written her account with a dual timeline, but to be fair, the majority of the book is devoted to the earlier time-period during the war. Although, I do concede that with the addition of the later timeline this reader was able to feel a sense of complete closure - Evelyn's story had finally come full circle.

Perfect pacing and character development, superbly well researched and written with accurate attention to historical detail - it's a testament to O'Brien's talent and skill as an author that her first attempt at this genre is five stars. Highly recommended.

With thanks to NetGalley and especially to Storm Publishing for the much appreciated arc in return for an honest review.

The Book of Lost Children was a well written and quite moving historical fiction novel by Jenny O’Brien that was inspired by actual events. It took place in Guernsey during the early 1940’s and in Dublin in 2018. The Book of Lost Children portrayed two strong, determined and intelligent women.

Evelyn Nightingale lived on the island of Guernsey during the Nazi occupation. Evelyn lived with her grieving father. Her mother had recently died and her father was having a hard time coping with her loss. One evening, when Evelyn was returning from a day out with a good friend, she witnessed a horrific scene. Right before her eyes, Evelyn saw bombs being dropped and too many injured and dead people. Evelyn felt compelled to display her knowledge of first aid and asked to help attend to wounds of the injured. She ended up working side by side with an ambulance man, Dave Le Page. He was so impressed with Evelyn’s skills, tireless dedication and commitment that he encouraged her to apply for a position at the recently established Emergency Hospital. Evelyn had previously worked at a school where she taught languages and music until the school was evacuated. Out of necessity and survival, Evelyn became a nurse at the Emergency Hospital. She was soon recognized for her bravery, quick responses in impossible situations and resilience. Evelyn was also a gifted violin player. Over her years as a nurse she saved and protected many new mothers and their babies. Evelyn even managed to hide several babies from the Nazis. She knowingly put herself in extreme danger when she committed these acts.

In 2018, Kitty White, was living in Dublin with her father. She was a thirty something woman who had studied art history and was presently working on her masters. Dressing the windows was one of her responsibilities as well as waiting on customers. Kitty’s mother had died so it was just the two of them. Her father owned an antique shop where Kitty worked with him. One day just before closing a tall, thin woman in her fifties with blonde hair brought in a very old violin that was not in the best condition. The woman had been left instructions to bring the violin to the antique shop owned by Kitty’s father. Kitty learned that the woman’s name was Caroline Raven. As Kitty examined the violin, its case and their condition, Caroline produced a notebook and pictures that she had also found in her attic near where she found the violin. There was also a signet ring in a velvet pouch and an old notebook with the name Miss E Nightingale on its cover. The pictures and the notebook upset Kitty’s father a great deal. Why? What could they mean?

The Book of Lost Children by Jenny O’Brien was both moving and extremely powerful. I have read other books in the past that took place on the Island of Guernsey but none that centered around the fates of babies and new mothers. It was full of secrets and intrigue. All of my emotions were tested by the scenes in this book. I really enjoyed reading The Book of Lost Children by Jenny O’Brien and highly recommend it.

Thank you to Storm Publishing for allowing me to read The Book of Lost Children by Jenny O’Brien in exchange for an honest review. All opinions expressed in this review are completely my own.

This the second of my two recent purchases and another powerful and moving story indeed. I had read other Guernsey stories that were eye opening and this one was no exception as it broke my heart once more. Those gutsy resisters, although nearly starved to death as the islands were cut off from mainland Britain and of course the German occupiers certainly didn't help! The senselessness of the war itself and desperation amongst the locals as they tried to survive was so imaginable as a reader. Another aspect hit me again in how many families were torn apart forever; 1,000s of orphans because of the war plus 1,000s sent from Guernsey to mainland England for a chance at possible survival. Oh the anguish parents and children suffered! Many children never had any idea of their origins as they were left on church doorsteps as infants.....

Anyway, excellent book and worth reading.

Historical fiction has to be one of the best genres in the world. I will die on that hill and defend it to the end. 😂

The Plot: Wow, what a ride! I was hooked from page 1 and anxiously awaited the end, wishing it didn’t end so I wouldn’t be heartbroken. I’m not saying why. You’re going to have to read it for yourself to find out. 😉😭 But the perspectives from Evelyn, a nurse amid World War II, and Kitty, a distraught daughter and antique shop owner in Dublin, flowed well and the pov switches weren't choppy or confusing, like a bad cut scene or fade out in a cheesy movie. Yeah, I’ve seen enough to know what those are like. 😂 The bravery, loss, heartbreak, and love within made this story so moving and helped me relate to and root for the characters. Some of the plot was predictable, but there were other parts where I was like, “No way!” Jenny O’Brien keeps you on your toes and I am so thankful for that because some historical fiction novels can be so predictable that it’s boring and bland. But not this book. Oh no. This was such a moving story and I want to read more of O’Brien’s works.

The Characters: We love a female character who isn’t annoying, don't we? 😉 Evelyn was a gem of a human being, a kind, beautiful soul. She cared for those in need, but had a feistiness deep down that appeared when someone was being a jerk or a monster. Kitty was the same and I honestly have no complaints about any of the characters. But the best part about these women was their love for music. I used to play the violin in my school orchestra. I hated it at the time because I was an insolent, dumb kid who didn’t value the beauty of playing an instrument, but all that to say I get giddy every time I read a book that talks about music or even the love of it, especially classical music. This book just mentions the love of playing music, but that’s enough for me to get hyped up about it. ☺️

The Writing: What can I say? Jenny O’Brien did an incredible job with the pacing, the flow, and the readability of the story. She is a fantastic writer and I look forward to reading her other books.

Overall Thoughts: This book was great. I teared up at the end and smiled warmly when I read the very last paragraph, knowing that things worked out in the end somehow, some way. It may not seem like it at the time and you may never see the happy outcome, but it’s always there. The light at the end of the tunnel. Hope. It’s a simple, four-lettered word, but man, it makes a world of difference in a devastated soul or a broken heart. I highly recommend this book and now I’m going to go cry. 😂

Evelyn Nightingale lived on Guernsey with her father, now her mother had died, and his grief hadn't left him. It was 1943 and the Germans had well and truly infiltrated the Islands, so with her father's work at the hotel curtailed, Evelyn volunteered at the hospital, her small amount of knowledge seeing her nursing the wounded and sick men, plus working in the maternity section, helping with deliveries, feeding the babies and more. Their rations meant they were hungry all day, every day, and their shifts were twelve hours and longer. Making decisions to save babies, saw not one, but three babies make their way to the nearby convent where Evelyn's aunt, Sister Therese, lived and worked. Keeping the secrets from the Nazis would be a death sentence if she was caught...

Dublin 2018 saw Kitty White coping with a father in grief, while she herself returned to their antique shop, in the wake of her mother's death. When a young woman brought a battered old violin in its case, desperate for it to be sold, Kitty bought it; before long she'd unearthed a hidden notebook, one which took her father deeper into his shell. Determined to find answers, Kitty headed to Guernsey and the aunt she knew was there.

The Book of Lost Children by Jenny O'Brien is a sad, yet heartwarming story, based on true historical events, which I loved. I've also loved the author's Detective Alana Mack series, so I'm now happy with another favourite author! Evelyn is an outstanding character, courageous, compassionate and caring, who hated the brutal Yannick, top German brass on the Island and a bully, but didn't cower to him. An exceptional read, The Book of Lost Children is one I recommend highly.

With thanks to NetGalley & Storm Publishing for my digital ARC to read and review.

Thank you to Netgalley and Storm Publishing for the advanced e-book copy.

The Book of Lost Children takes us through dual timelines - During the 1943 Nazi occupation of Guernsey and in present-day 2018.

1943: Nurse Evelyn Nightingale risks everything by hiding three babies from the Germans. Evelyn must be extra careful now that a German commandant is growing increasingly suspicious of her.

Present Day: Kitty White is taking over the family antique shop when a woman sells her an old violin out of desperation. Upon further inspection, Kitty discovers a list of names hidden in its case. This leads her to Guernsey, where she uncovers deep family secrets.

Inspired by true events, Jenny O’ Brien, did an amazing job with her research. This is an emotional read so have your tissues ready. I enjoyed this book, and I loved how the past and present came together perfectly in the end. I highly recommend it!

This was quite a story! The things people had to endure during the war with Hitler were unimaginable. This story tells of one woman’s efforts to correct, as much as she was able, some of those wrongs. The story is well written and very descriptive. I was given a complimentary copy.

This was a very interesting and powerful story set in Guernsey in the Channel Islands during the second World War. The Germans had invaded the Islands and were making their presence felt in all ways. I enjoyed this very much. The pace didn't let up at all. My thanks to netgalley and the publishers for giving me the opportunity to read this book in return for an honest review.

This story had it all. The good side and bad side of love (maternal and romantic) in a war torn world because of Nazi occupying Guernsey.
I glimpsed parallels between the brave nurse who risked it all to protect innocent babies and Camille—a woman who survived because of her beauty and certain … abilities. I didn’t expect to come to care for Camille so much, but her heart gutting story, and the other mothers’ stories as to why they couldn’t care for their children were so beautifully, and tragically written.

“I don’t care about myself but my son deserves a future without a monster in it.’

There were so many amazing lines in the story, but I picked that one, and would love to see this story as a film. (I don’t say that often, but this would make a great movie)

I was given a complimentary copy of this book from Netgalley and the publisher. All words are my own.

I gave The Book of Lost Children four⭐️⭐️⭐️⭐️ Thank you Net Galley, Storm Publishing and Jenny O’Brien for this ARC. These are my honest opinions.

I really enjoyed this book. While it was not as heavy or soul clenching as some books with a WWII story, especially involving a nurse saving babies, it was still a great book! And it’s inspired by a true story.

I was able to identify with each of the characters and to watch them grow and develop. It is a dual timeline, but is mostly set in the 1940s in Gurnsey on the Channel Islands.

I also like how everything was wrapped up in the end. Overall, an enjoyable book.

The Book of Lost Children is a compelling and captivating read that I wont soon forget.

The story is told in two time lines.

1943 in Guersney we meet Evelyn Nightingale working as a nurse in the German Occupied island.

Tension mounts every day with the German presence, food is scarce and the hosptial team does the absolute best they can possibly do.

Evelyn thinks quickly on her feet and several times comes up with plans to thwart the Germans including hiding three babies.

Too many people know her secret..

Secrets have a way of blowing up in your face.

I cheered for Evelyn, cried with her but most of all admired her strength and resilience

1948 there is Kitty White buys for her antique store an old German viiolin with a hidden compartment.

She realizes her dad recognizes the instrument. Kitty is determined to get to the bottom of the story and it the story the violin will tell.

Jenny O'Brien does an amazing job of bringing the two stories together.

The book is beautifully written and I felt like I was right there with both ladies.

The Book of Lost Children is a gripping read based on a true story and I found it impossible to put down.

Thanks to NetGalley and Storm Publishing for the privilege to read and review The Book of Lost Children and most of all introducing me to Jenny O'Briens books.

The Book of Lost Children by Jenny O’Brien is set during two time periods, WW2 in Guernsey and 2018/19 in Dublin. Kitty is minding their store in the present day. Her mother had died 12 months before and her father is not handling her death very well. A woman brings in an old violin hoping to sell it. Her mother had been the expert in musical instruments, but the violin tugs at Kitty and she thinks she may start playing again. With the old violin are a few photos, a notebook and a ring. The name on the notebook is E. Nightingale. And so, the past comes into play. This book grabbed my interest from the very beginning. The changing of society rules with WW2 and women finding their place in the new times is shown quite clearly. Evelyn Nightingale’s relationship with her father would be the same in many homes at the time. The issues of medical care and supplies as well as food supplies during the Occupation of Guernsey, and beyond, make for a gripping story and pulled at the heartstrings. Together with saving babies born during this time, it makes for harrowing reading. This is very well written, blending fact with fiction. It kept me glued to the page.

The past and present come together in this historical fiction read by a new to me author. It was gripping, and I couldn't put it down. It was full of angst, scary moments, and long-buried family secrets.

Evelyn Nightingale is a nurse in Guernsey, which was occupied in the 1940s. She risked her life to protect mothers, and their newborns abd faced danger while doing so.

The tension is unmistakable as Evelyn lives her life under constant surveillance. The fact that discovery could mean death for her and the babies she has to protect.

Meanwhile, in present-day Dublin, Kitty White finds a hidden list of names inside an old violin case, which makes her go on a journey to uncover the truth about her family’s past.

Evelyn was a true hero. Her character had me rooting for her from the start, and I loved reading about her emotional, desperate, and scary journey.

If you like historical fiction, I'd recommend this for sure.

Well, this certainly got all the emotions going!

Inspired by a true story, this is a tale told in dual POVs, over dual timelines and locations of WW2 in Guernsey, and 2018/19 in Dublin, Ireland

In the more recent time, Kitty is minding her family store. A store of curiosity, full of pretty much anything and everything. Her mother passed away a year before, and her father isn't handling it well, leaving Kitty to run the shop. When a woman appears just before closing, wanting to sell an old violin, in desperate need of repair, Kitty decides to take it off her hands, a self bought Christmas present to her from her father.

On Christmas day, on examining the case, some photos and a notebook are revealed. It's clear her father recognises the photos but shuts the conversation down completely. It's not until she visits her aunty who has recently taken a tumble that she learns who these people in the photos are and the names in the notebook are brought to life.

Ww2, Guernsey, and Evelyn Nightingale, once a primary school teacher is now working as unofficial nurse. Working tirelessly to help those most in need, Nurse Nightingale soon becomes a hero without realising just how many lives she will save. With her pure heart, quick thinking, and bravery, she goes above and beyond to keep the needy safe, even at the detriment of her own health and safety.

It is a story of true resilience, bravery, and kindness. This seriously pulled at every heartstring. Knowing that during the war, there were real people out there, doing everything humanly possible to save others. With little or no medical supplies, little food to survive on and sparce belongings to hold on to. It shows just how strong friendships could truly be, even when times were at their bleakness.

This was an intricately weaved tale where two lives come together, connected by time and all revealed by an old violin.

I can't begin to imagine what it was like during the German occupation of the Isle of Guernsey. I can't being to imagine the difficulties of those left behind, forced to live under their rule. I can't begin to imagine the health issues the citizens of Guernsey while the German soldier had access to drugs and medical supplies. Where my imagination fails me; Jenny O'Brien words allowed me to witness the horrors.

The dual timeline uses a violin case to transition between time periods. A violin sold to antique store in present day Dublin hold the secrets to three children born on Guernsey during the occupation. Their only crime was having German fathers. Thanks to Evelyn Nightingale the children were never whisked away to Germany to become part of the Aryan race.

The Book of Lost Children tells of the horrors on Guernsey. Through Evelyn's eyes the reader sees the affects the German occupation. My tears flowed freely on more than one occasion. Evelyn's determination to save the babies was inspirational. I couldn't help cheering every success. Evelyn's job as a nurse gave witness to the suffering, the illness, the helplessness. My heart broke.

Learning of what happened to the children was facinating, Their unique situation led them in different directions. Their unique situation tells the story of determination. The violin brought the past into the future. As a reader I am reminded that to have a future we must never forget the past.

Inspired by true events, this is a compelling tale
of two women separated by time, but
connected by secrets and acts of courage


Set across two timelines, we meet Evelyn
Nightengale, a school teacher, turned the nurse in
1943, during the Nazi occupation in Guernsey
She is such a fascinating, heroic character
whose journey is gripping and emotional and
her determination to hide and protect babies
as well as their mothers from the Germans,
was inspirational.


In the present day, we meet Kitty, who discovers
some hidden secrets in an antique violin case.


Jenny's skillful writing vividly portrays the
atrocities of the war and characters that readers
will deeply connect to.


While this is a story of heartbreak and sorrow, it
is also about resilience, bravery, and above all
else, hope. I was so invested in this tragically
beautiful story and give it a solid 5%, If you love
historical fiction, this is a must-read.

This was one book I couldn’t put down. Evelyn Nightingale is on Guernsey when it is occupied by the Germans. Through need to survive, she takes up a role at the hospital. Her quick thinking saves Colin, the escaped prisoner and several babies from being scooped up by the Germans. Fast forward to 2018, where the secrets come out, as they were hidden in a violin case, and the background of the saved children comes out. The scenes set in the war are especially poignant, as the threat of German violence and discovery increases, as well as the harsh conditions the locals had to survive. My only quibble is that it is based on real events, but the author hasn’t explained what was historical fact and what was fiction. Other than that, what an awe inspiring read, and how strong and brave people can be. Thanks to NetGalley and Storm Publishing for the opportunity to read and review this book.

Just read the book of lost Children by Jenny O’Brien, and I’m still reeling from the experience. This historical fiction novel, set during World War II, is based on real events that took place during the German occupation of the Channel Islands. The story follows Evelyn Nightingale, a nurse with a secret that could put her life at risk.
What struck me most was how vividly O’Brien brought the past to life. The historical details were meticulously woven into the narrative, making it feel both authentic and immersive. The dual timelines added depth to the story, slowly unraveling the mysteries and secrets that Evelyn kept hidden.
What’s truly astonishing is that this isn’t just a fictional tale; it’s rooted in real historical events. The fact that such stories actually occurred during World War II is both heartbreaking and awe-inspiring. It’s a testament to the resilience and courage of those who lived through such times.
The book was engaging from start to finish, with moments that left me on the edge of my seat. While some parts were slower-paced, they were necessary to build the tension and emotional impact that followed.
Overall, The Book of Lost Children is a gripping and emotional read. It’s a reminder of the power of historical fiction to educate and move us. I highly recommend it to anyone interested in World War II history or those who enjoy a compelling narrative with strong historical roots.

The Book of Lost Children, written by Jenny O'Brien, is a great WWII historical fiction book based on a true story. It reads as a dual timeline, the 1940's in the Channel Islands and also in 2018/19 in Dublin.

In Dublin in 2018, Kitty White, who lost her mother 12 months earlier, takes on keeping the family antique store open. Her father is still grieving the loss of his wife and is struggling to move on. Kitty's mother was an excellent violin player so when one day a woman brings in an old violin to sell, memories surface of her mother and she buys it on the spot. Kitty plays the violin as well and thinks maybe she might start playing again. Looking at the violin, she knows they won't be able to recover much profit from it... or will they? Upon examining the violin and case, she discovers some photos and a notebook with the name E. Nightingale on the cover. In the back of the notebook is a list of names. This begins her search to find out who these people are listed in the notebook.

How does this violin connect the past to the present?

In Guernsey in 1943, nurse Evelyn Nightingale is employed by Emergency Hospital and eventually she is transferred to the OB ward. She is a simple nurse and becomes a quiet hero! One day a mother dies in childbirth leaving a baby behind and the father is unknown. Evelyn hides this baby to save it from the hands of the Nazis. Only few know her secret. She records the name of the baby and the mother and father, if known. She hides the notebook in her violin case. Such courage from a nurse who knew she needed to save this baby. Does she rescue other babies from the ward? What happens to these babies? Are they still alive today?

Kitty White begins to uncover the secrets of the notebook. How does her father feel about this? This is a story that you'll want to keep turning the pages to find out what happens and how these lives connect. Jenny O'Brien put much research in this and delivered an astounding story.

I received a copy of the book "the Book of Lost Children" by Jenny O'Brien, from NetGalley. The book takes place in two different time eras. In 1943 Evelyn is trying to survive during World War 2. She had been a teacher but ended up helping nurses. She starts helping a patient who is accused of being a spy by hiding him. She eventually ends up in the Maternity ward. She witnesses a young girl giving birth and dying she sees this baby is part of the "master race" program started for Hilter. She saves the baby, and decides to save other babies to keep them from the horrors of Hitler.
the second era takes place in 2018, Kitty helps out her dad in the store they own. They buy used items to sell in the store. When a person comes in to sell a very old violin she reluctantly buys it. When she further inspects the violin there are some papers and a notebook hidden in the violin and case. It has names of "lost children" very mysterious things written in the notebook. This has the name of Evelyn in the violin. Now KItty wants to know who is Evelyn? what do these names mean? the book goes back and forth focusing on Evelyn and how she helped babies to protect them from HItler's plan. and How Kitty from 2018 tried to find out what happened to Evelyn and the babies she tried to save. A very good book. Although the characters are fiction it is based on real events that happened during the Holocaust and World War 2.

Inspired by true events, The Book of Lost Children takes us through dual timelines. Nurse Evelyn Nightingale leads us through the tragic scenes of Guernsey during Nazi occupation. Kitty leads us through the year 2018, as she makes discoveries that bring her family back to secrets of their past.

Evelyn’s story is compelling as she risks everything to hide three babies from the Germans. Along the way, a German commander is suspicious of her actions and always keeping an eye on her. As a teacher before the war, we have the privilege of seeing Evelyn put compassion and empathy first on every occasion.

This leads us to 2018 where Kitty is presented with an old violin as she is taking over her family’s antique business. Her investigation leads her and her family back to Guernsey to piece together a beautifully unexpected history.

I loved how Jenny O’Brien painted each scene in this book to recount a story based on real events. There were many characters, but they all held an important place in the story.

Thank you to NetGalley and Storm Publishing for the opportunity to read this book in advance.

If you’re a historical fiction fan you should definitely check this one out. A WWII novel from a perspective I’ve never read before- the story of a nurse in occupied Guernsey and her experiences of love, loss, and humanity. The author does a great job of connecting Evelyn’s wartime story to Kitty’s in present day. Makes you remember that these stories of war time really weren’t that long ago after all. The twist in this novel wasn’t revealed until close to the end and wasn’t easily predictable which I always appreciate!

I have tremendously enjoyed this story! Knowing that it is based on the life of a real woman makes the novel even more interesting and captivating. The plot was full of tension, and the two timelines worked very well. The only detail I found totally unnecessary is Kitty's burgeoning romance . To me, it did not bring anything to the story and rather disturbed the smoothness of the plot.
I have read many of the author's crime books which I also enjoyed a lot. Still, this novel was a brilliant change and I hope she writes more historical novels beside her crime books.
I received a digital copy of this novel from NetGalley and I have voluntarily written an honest review.

✨BOOK REVIEW✨THE BOOK OF LOST CHILDREN by Jenny O’Brien

Kitty, who runs a family owned antique business, acquires a worn violin and other items. What she discovers will forever change not only her life, but the life of others she cares for so deeply.

The violin transports readers back to 1940, to the life of Evelyn. Evelyn becomes a nurse during the changing times due to WW2. She not only is a nurse, but an angel for those who need her help most during the time the German soldiers occupied parts of Guernsey. Evelyn risks her life time and again to help make a better life for others.

The Book of Lost Children by Jenny O’Brien is told in dual timelines. Kitty’s life in 2018 and Evelyn’s life in 1940. The pages of this book keep flipping as readers are immersed in the lives of these two women, until ultimately revealing their connection. This is a very different WW2 historical fiction novel unlike anything I’ve read. O’Brien paints a different sorrowful tale about the mothers who gave birth during this time. What these women went through was terrifying to say the least. The bravery of these women, their individual stories, the choices they made, the extreme risks they took, is like nothing I could imagine having to live through. What these women saw and experienced is truly unfathomable.

I am thankful for authors like Jenny O’Brien for bringing these historical fiction stories to life for us to read. These incredibly brave women, men, and families should never be forgotten for their selfless acts, their extreme kindness, and how they were there for each other, trying to make other people’s lives better, while sacrificing their own. The stories of these people are unforgettable.

Read this book. Take in its history. Let the emotions hit you wave after wave. It’s the least we can do for these selfless people who lived during this time. Hear their stories. Share their stories. Learn from their stories.

Thank you to NetGalley and Storm Publishing for providing me and allowing me the honor to read an ARC in exchange for my honest opinion. This book is out for publication today, April 11, 2025.

The Book of Lost Children by Jenny O’Brien is a fictional historical tale based around a true story.

The book is set between present day Ireland, or close to it, and flips back to World War 2. The story follows a woman as she discovers family history that she never knew about, and as she discovers it in the present, we are transported to the past, with bombings, air raids, and an oppressive regime. I have always had an interest in history, and historical fiction is a great way to mix both. The story is delivered in slow steps, as you follow Ms Nightingale, who just so happens to be a nurse, and her journey working with the residents of her town and dealing with the soldiers that are everywhere. The book paints graphic pictures of the poverty they suffered as well as the steps many had to take to survive.

Jenny O’Brien weaves a realistic sad emotional tale, enhanced by the knowledge that it’s based on actual occurrences, makes this an emotional roller coaster ride. I read a lot, and the last several chapters hit my soul. This will be one of those books that leave you thinking afterwards. The contrast with the past and the present just reinforces the limited choices that they had in the past, but showcased how one small thing, to one person, can literally be their entire existence. This is definitely a book I would recommend and I intend to check out more of her books, especially if she writes them with the same passion.

Occupied Guernsey during World War II

The islands of Guernsey were occupied by the Nazis during World War II. The population suffered and were under the yoke of an unforgiving invader.
Evelyn Nightingale lost the love of her life, Joseph in the early days of the war. Through a series of happenings she’s now nursing (not registered) at the Emergency Hospital in Câtel.
It’s here she meets the pregnant collaborator Marise and her friend Camille. Marise is having a child to an SS officer. An angry man who wants his unborn child to be sent back to Germany to become a child of the Reich.
Why these things happen are never straightforward. Unerlieutenant Jannick Klein is a dreadful man. He has the habit of beating his women when they didn’t please him.
Evelyn is determined to help thwart him.
Fast forward to Dublin of 2018 and we have Kitty White, an antiques and second hand dealer, buying a violin from a woman off the streets. It helps the story come full circle. Evelyn Nightingale had been an accomplished violinist.
It’s when Kitty looks at the violin case that she discovers a history of her own that she’d known nothing about.
The execution of the plot is seamless, the tale unique. Violence against women plays its part with the particular SS Officer involved so could be a trigger.
This is a heart stopping read.

I love a good historical novel and for one set in the Channel Isles this was always going to be a winner for me.

This is a dual plot line set in Occupied Guernsey and current day Ireland.

I found a lot of the current day plotline I could have done without. I also found some of the characters being one dimensional especially the German captain who I think I have met in may books. Angry and in a uniform.

I got past this though and found myself fully immersed in the WW2 plotline. The civilian bravery shown by the occupied populace is awe inspiring, and also at times hilarious.

The reason its three stars as I felt it could have done with less or even none of the present-day thread in Ireland. The WW2 plotline was real with characters whose lives I was invested in.

This book is told from two different points of view. Evelyn is a school teacher turned nurse. During World War II, the island of Guernsey was taken over by the Germans. This is the story of how the islanders survived the war. Kitty's portion of the story takes place in present day Dublin. A woman comes into her shop and sells her an old violin. In the case's lining is a photograph, a child's exercise book and a signet ring ...
I enjoyed this book very much. World War II is my favorite genre, and it was very interesting to learn more about Guernsey during its occupation. Highly recommended.

Thanks in advance to NetGalley for providing me with an advanced copy of this book.
