Another unforgettable, powerful and captivating read by Siobhan Curham! This talented author continues to impress and inspire me with her gripping stories.The Lost Story of Sofia Castello is a unique and passionate WW2 focused tale that pulls on the heart strings with gusto! This energy charged, emotional drama with its mysterious plot had me glued to the pages. There are heaps of twists and turns that left me breathless. Siobhan draws upon her own experiences with Portugal, its people, history and landscape—making The Lost Story of Sofia Castello feel incredibly authentic.

Although the novel is filled with secrets, misunderstandings and shocking betrayals, there are some joyous developments along the way, too. But the traumatic years and events of WW2, were painful to read. It was easy to imagine what it must have been like to endure the bombings in London. I found Siobhan’s vivid descriptions reflected the tone and torture and I could even hear the piercing sirens and rains of bombs. Scary times. But in those awful moments, people connected and dealt with their fears in unusual ways as seen by character Trafalger. I won’t give anything away but look for it during those scenes when Sofia relates their time together in those first days.

I could appreciate the song writing aspects of the story since I do a lot of collaborating myself. I truly know how inspiration for songs can come from many sources. It was interesting to see how Ocean Longing came to be through a romantic rendez-vous of Sofia’s. This powerful attraction translated beautifully across the world in music and listeners adored it for various reasons. But when things went wrong, the song raised painful reminders in Sofia’s heart. For we bring our experiences, whether good or bad, to a song both as the creator and as a listener. When Lily hears the song, it reminds her of her failed relationship and loss—when she feels betrayed by her own body. Poor past relationship experiences can darken a person’s perceptions, making it difficult to recognise or accept something good when it comes along. So yes, we are shaped by our past and although we must learn from it—we must not expect that everything will turn out the same in the future. For if we hold on to that rigid view, we may misinterpret what comes our way.

One phrase, thought or tidbit of wisdom that stands out in this novel like a shining star on a dark moonless night is something singer Sofia shares with ghost writer Lily: ‘sometimes the things that seem like the end of the world are actually the prologue for something truly delightful…’ Things don’t always work out as planned and sometimes it is just as well they do not. Because they are paving the way for something better. Trials are not fun but they sharpen us and can make us more resilient. These words spoken to Lily by Sofia certainly resonated with me as I have found this to be so as well.

And I loved listening to Sofia tell her story of how she dealt with the war years. She was strong and brave in many ways. And although it was painful for her to resurrect those memories, it provided a healing eventually that caused her to question her perception of events. I thought Sofia writing a book about her War years is a creative way to provide another perspective on the events of the past.

The whole structure of the novel is cohesive. The plot has plenty of tension and mystery which results from us being given a series of bread crumbs along the way that lead up to massive revelations. The pacing is perfect, the setting is atmospheric and sometimes explosive (literally!), and the main characters are relatable and dramatic. And there’s lots of exciting action and surprises!

There is a wonderful cast of characters. I practically enjoyed Lily, Sophia, Gabriel, Trafalgar and Jane with their flaws and strengths. I loved the ending and felt satisfied with how the various strands came together and feasted on the twists, turns and surprises! The meaning of family is explored and how blood is not always the force that brings and holds people together. Sometimes having other common ingredients can create something new.

This story dug deep into my heart and caused me to feel great emotions. It also captured my mind and made me think about possible scenarios. I absolutely loved The Lost Story of Sofia Castello. Huge thanks to Siobhan for taking me on another unforgettable adventure. This is passionate, powerful, profound fiction. I look forward to the next instalment from this amazingly gifted author who is both courageous and highly dedicated to her craft. 5 Glorious Stars ⭐️⭐️⭐️⭐️⭐️

Thanks to Bookouture and Netgalley for the ARC.

I was completely drawn into The Lost Story of Sofia Castello. The dual timeline weaves together war, secrets, and resilience so beautifully. Sofia’s story is tense and heartbreaking, while Lily’s modern journey of grief and reinvention is just as compelling. The mystery kept me hooked, but it’s the emotional depth that really lingers. This book makes you think about loss, survival, and the unexpected ways we heal. Absolutely loved it!

Back in 1941, singer Sofia Castello was mourned by the world following her death after the plane she was in was shot down by Germans.

Lily Christie is a ghost writer and her agent, Jane, calls her to a meeting for a secret job. Lily will have an expenses paid trip to Portugal with the possibility of ghostwriting Sofia Castello’s life story. Now in her eighties, Sofia is alive and well!

Following a rough time since splitting with her husband, Lily jumps at the chance of a break, but to also find out why Sofia faked her own death.

What a beautiful story this is, I found it emotional at times.

The story is told over a dual timeline. We follow Sofia on her journey to stardom and beyond.

It was difficult hearing Sofia’s story as she tells it to Lily. There were some touching and tender moments throughout the book.

The ending was not what I was expecting at all, it had a great twist to it.

A beautiful tale of bravery, secrets, revenge and romance.

My thanks to Bookouture and NetGalley for a copy in exchange for my honest review.

A nice story told in a dual timeline. The older one set during WWII is more interesting than the modern one (2000). Unfortunately, the modern part breaks the little tension there is in the part telling Sofia's story life. You will find in this novel what you usually find in a dual time story: romance and secrets. With a few red herrings (that was good), this story is light-hearted. I like Sofia's no nonsense temperament, while Lilly annoyed me a bit with her personality being rather weak and not much will to fight. Overall, a story for the heart, rather than about a world of spying!
I received a digital copy of this novel from NetGalley and I have voluntarily written an honest review.

The Lost Story of Sofia Castello is a haunting, emotionally charged dual-timeline novel that explores the ripple effects of war, the resilience of women, and the cost of long-held secrets. Siobhan Curham delivers a story that feels both sweeping and intimate, with a mystery at its core that keeps you turning the pages while the emotional undercurrents keep you rooted in the characters’ journeys.

At the center of the novel are two women—Sofia Castello, a glamorous and enigmatic singer believed to have died in 1941, and Lily Christie, a struggling writer trying to piece her life back together. When Lily is hired to ghostwrite Sofia’s memoir, she expects a simple job. Instead, she discovers that Sofia is alive, living in hiding in a quiet Portuguese coastal town, and finally ready to reveal the truth about her past. Or at least, some of it.

As Sofia recounts her harrowing life during WWII—singing for Gestapo officers by night while secretly helping the Allies and caring for a young orphaned German girl—Lily is pulled into a layered, suspenseful story of love, danger, betrayal, and impossible choices. But as the memoir unfolds, it becomes clear that Sofia is still guarding her most painful truths. Why did she fake her own death? Who is she still afraid of after all these years? And why, really, did she choose Lily for this task?

The novel alternates between the 1940s and the year 2000, with both timelines delivering rich, emotionally resonant stories. Sofia’s narrative during the war is filled with tension, sacrifice, and moments of defiant humanity. Meanwhile, Lily’s modern-day chapters explore grief, personal reinvention, and the way stories—our own and others’—can help us heal.

Curham’s writing is elegant without being overly sentimental. The characters are deeply human, with flaws, fears, and moments of grace that feel authentic and earned. The relationship between Sofia and Lily is the emotional core of the novel—built on mutual vulnerability, shaped by generational differences, and ultimately transformative for both.

What makes The Lost Story of Sofia Castello stand out is how it balances suspense with emotional depth. The secrets Sofia keeps feel like they matter. The slow reveal of truth is both satisfying and surprising, with stakes that rise until the final, poignant twist. The setting—split between the golden light of coastal Portugal and the shadows of war-torn Europe—adds richness to the atmosphere and emotional weight to the narrative.

This novel asks powerful questions: What do we owe to the truth? How do we live with the choices we’ve made? And is it ever too late for redemption?

If you enjoy historical fiction with emotional resonance, mystery, and fully realized female characters, this is a must-read. It will stay with you long after the final page.

Perfect for readers who love:
• Dual timeline narratives
• WWII espionage and intrigue
• Female-driven stories
• The redemptive power of storytelling
• Found family and unexpected friendships
• Themes of identity, grief, and second chances

Thank you NetGalley and Bookoture for my ARCof this beautiful book.

The Lost Story Of Sofia Castello by Siobhan Curham is a totally gripping dual timeline novel that I adored. It is set in 2000 and during the war years, mainly in Portugal.
We see that secrets that have been kept for over fifty years now need to come to light. Fact is stranger than fiction, and I confess to reading with dropped jaw as the book sped towards its conclusion.
The war years were a time of fear and suspicion. There were agents and double agents, and the Gestapo, all lunching in plain sight. As Siobhan Curham sets the scene, my heart rate and pulse rate rose.
We see that friends are born in adversity as a young singer puts aside all thoughts of personal safety in order to rescue a young Jewish girl from the clutches of the Gestapo.
There are all the wasted years as we ponder on what might have been.
Portugal is a vibrant place, even in times of war. The golden sands and the heat contrast sharply with the grey London skies.
Characters maintain their joi d’vivre even into their eighties, persuading others to abandon their straight way of thinking, throw caution to the wind, and dive into life.
The novel alternates between the two time periods as an octogenarian opens up her life story to a ghost writer.
All the characters were well drawn and believable.
The whole story was mesmerizing and I didn’t want it to end. The Lost Story Of Sofia Castello is a page turner that will capture your heart as you read.
I received a free copy from the publishers. A favourable review was not required. All opinions are my own.

4/5 stars.

Cover art is very attractive, although the image of a woman with her back to the viewer has become over-used and boring. The warm orange and brilliant blue immediately bring to mind the vibrant atmosphere of Portugal.

Siobhan Curham tells a compelling and relatable story about ghostwriter Lily Christie, who is struggling with the twists and turns of life when she is given an amazing opportunity--to ghostwrite the memoirs of a *woman who died over 60 years ago*! But Sofia Castello, whose singing talent enthralled the world, did NOT die in the 1941 plane crash and now she is ready to tell her story.

I enjoyed learning about the culture of Portugal in the 1940s, its role in WWII, varinas, and fados.

I found the relationships between the characters shallow and under-developed. That was frustrating; hence the loss of a star.

Writing and story good enough I would read more of Miss Curham's titles.

Thank you to netgalley for letting me read this e arc in exchange for an honest opinion.

From the very first page of this book, I was stunned, mesmerised. Written with a ferocious passion that'll knock the wind out of you!
I’m so sad it's over. I could have read another sixty chapters . . . A fantastic read!

This novel is full of dreams, betrayal, secrets, forgiveness and the past that binds people.

Lily Christie is a writer who gets the chance to write a memoir about Sofia Castello. She was well known during the war as a singer who died tragically in 1941.

What the world does not know is that Sofia is alive and ready to tell her story. She is now in her eighties and the truth will come out.
Discovering love during war lead to complications as she finds out she was betrayed.

All these years later we hear Sofia’s story. This quote from the novel is compelling. “Sometimes the things that seem like the end of the world are actually the prologue for something truly delightful.” An ending can become a new beginning. A moving story that I highly recommend to EVERY historical fiction fan.

Premise
A famous singer from the WWII era comes back from her faked death and hires a ghostwriter to tell her story. The book interweaves themes of grief, second chances, and what it means to be successful alternating between past and present time periods. The past storyline follows the story of Sofia Castello and the mysterious events leading up to her faking her own death. The present storyline is about Sofia’s story being told and the ghostwriter, Lily, reflecting on her own past and present.

Add to your TBR if you love:
The power of the arts & singing
WWII themes
Strong FMCs
Found family
Grief and lost love

What worked well
The plot definitely keeps you guessing all the way through and the story unfolded at a good pace. The duel storylines between the writer and the singer kept me engaged in both past and present chapters. After the first few chapters I was pretty invested in seeing what would happen next and what parallels would be drawn between Sofia and Lily.

The book definitely leaves an impact in that it makes you think deeply about betrayal, forgiveness and grief. While also seeing how each character takes solace in music, plants, swimming, or yelling out at the ocean. It gives the reader space to think about if they were catapulted into dark times, how would they respond, and how would they find the light?

The most endearing parts for me explored the timeless friendships that endured so much.

Rating
Overall, the book was an enjoyable read. It keeps you just the right amount of hooked at the end of each section. Definitely check it out once released!

Quick disclaimer, I am new to the world of book reviews. This review reflects my personal opinion and experience with the book. I received a free copy of this book in exchange for an honest review.

Oh how I loved this book.

The relationship between Sofia and Lily was amazing and I loved their similarities and their differerences.

Sofia is writing her memoir and her 80 years have been filled with tragedy love and many worldly experiences.

Lily is her ghostwriter, and she has also had difficulties that she is trying to get over.

This is beautifully written, wonderfully told and I absolutely was lost in the tale .. It's sublime

This is the eighth book I’ve read by this author and she continues to amaze me with her unputdownable books and her ability to transport me to a different era and help me understand how it felt to live at that time.

One theme of this book is blessings in disguise. At 80 years old, Sophia Costello looks back on her life and learns to see the gift in heartache. In helping Sophia step out of the shadows and set aside her need for revenge, her ghostwriter, Lily Christie, gets balm for her own disappointment. The two bring each other back to life and ignite in each other the power to step into the future with hope and determination.

Curham also channels the power of hindsight. Until Sophia begins the arduous task of compiling her memoir, she only sees a broken relationship with the love of her life. The process brings her to a place where she admits to being broken apart so that she can mend completely together. I like that thought. Despite lost time and opportunity, we can be stronger as a result of the journey.

If this 5-star inspirational journey isn’t on your reading list, it needs to be.

I was gifted this copy by Bookouture and NetGalley and was under no obligation to provide a review.

*I’d never heard of Cockney rhyming slang as part of the London dialect. I found myself down a rabbit hole!

Beautifully written. This historical fiction will draw out the whole range of emotions. While exploring timeless love and friendships, heartache, rebuilding and the impacts of war time you'll also have no shortage of surprises along the way.

Thank you to netgalley for letting me read this e arc in exchange for an honest opinion.
