Genre: WWII Thriller

Some debts survive captivity. Some brothers never stop looking.

France, 1943. SOE operative Derrick Sedgley is running for the Spanish border with Lotte Braun: a German woman, an unlikely ally, and a complication he never saw coming.

Behind them, closing fast, is her brother.

Ernst Braun is a Luftwaffe pilot who woke up in a British hospital bed and spent two years deciding who put him there. All he had asked for was one more hour of daylight. Now he wants his sister back. He wants Derrick dead. The SS officer travelling with him has a simpler agenda: he wants them all dead.

The Pyrenees are ahead. The border is possible. Not everyone will reach it.

One More Hour of Daylight is a taut, morally complex WWII thriller about promises made in good faith, debts that survive captivity, and what it costs to bring someone safely home.

One more hour of daylight. That was all he asked for.

It was never going to be enough.

Every so often, a book comes along that reminds you exactly why you fell in love with historical fiction in the first place. 'One More Hour of Daylight' by C.M. Gray is one of those rare novels. Rich in emotion, beautifully researched, and impossible to put down, it is a story that captivated me from its opening pages and stayed with me long after I had finished reading.

Set against the backdrop of the Second World War, the novel follows Derrick, a young man whose life is shaped by a decision made in the earliest days of the conflict. As the war unfolds, he finds himself drawn into a dangerous world of espionage, resistance networks, and impossible choices, where courage, loyalty, and compassion are tested at every turn.

One of the novel's greatest strengths is its characterisation. Derrick is an exceptional protagonist—not because he is fearless or larger than life, but because he is wonderfully human. His quiet determination, compassion, and unwavering sense of duty make him someone you cannot help but root for. Every decision he makes carries weight, and his development feels authentic from beginning to end.

Lotte is equally compelling. She is intelligent, resilient, and beautifully written, with a depth that makes her far more than simply a companion to Derrick's story. Her own experiences are every bit as engaging, and together they form the emotional heart of the novel. Their relationship develops naturally through shared experiences, trust, and mutual respect, making it feel genuine, heartfelt, and entirely believable.

The supporting cast is superbly realised. Every character, whether ally or adversary, feels like a fully formed individual with believable motivations. Even those who appear only briefly leave a lasting impression, adding richness and authenticity to the narrative.

C.M. Gray has an extraordinary ability to build tension. Whether the characters are navigating occupied territory, relying on strangers, or facing split-second decisions, there is a constant sense of uncertainty that keeps the pages turning. At the same time, the quieter moments are just as absorbing, allowing the characters to breathe while giving the reader time to appreciate the emotional impact of their experiences.

What impressed me most, however, was the emotional honesty of the novel. This is not simply a tale of wartime missions and dangerous assignments. It is a thoughtful exploration of guilt, forgiveness, sacrifice, and the resilience of the human spirit. It asks difficult questions without ever offering simplistic answers, trusting the reader to reflect on them long after the final page.

The historical detail is exceptional. It is clear that extensive research has gone into every aspect of the novel, yet the history never overwhelms the narrative. Instead, it provides a vivid and authentic backdrop that enriches the characters' experiences and brings the period to life with remarkable clarity.

The pacing is excellent throughout. There is a wonderful balance between moments of suspense, quieter character-driven scenes, and thoughtful reflection. Every chapter left me eager to read the next, making this one of those books that is incredibly difficult to put down.

Beautifully written, immersive, and deeply moving, 'One More Hour of Daylight' reminds us that history is shaped not only by famous names and great battles, but by ordinary people faced with extraordinary circumstances. The characters feel real, the emotions ring true, and the story lingers long after the final page has been turned.

C.M. Gray has crafted a compelling and thought-provoking novel that balances historical authenticity with unforgettable storytelling. It is a book that will appeal to fans of intelligent, character-driven historical fiction and one that I would happily recommend.

C.M. Gray

C.M. Gray's first book, The Flight of the Griffin, was longlisted in the 2015 Times Chicken House Writing Competition. Shadowland, the first book in the Pendragon Saga, has so far received over 900 five-star reviews on Amazon. These things still genuinely astonish him, and he is deeply grateful for every one of them.

Most of his previous work has been fantasy: either pure fantasy or historical fantasy, the kind of writing where druids turn up uninvited and one of your main characters develops an unsettling affinity with wolves before you have quite decided what sort of book you are writing. Shadowland began with every intention of staying grounded in historical reality, the story of Uther Pendragon. It did not. It has turned out to be a popular book, so he does not complain.

His years travelling through Asia, India, Africa and the Middle East have a habit of finding their way onto the page. He has seen and done some fairly strange things along the way and met some extraordinary people, and writing fantasy has always felt, to him, only a short step from writing fact.

New for 2026

One More Hour of Daylight, marks C.M. Gray's return to writing. It will be fully published in June 2026, marking a departure: pure historical fiction, no druids, no wolves. It follows Derrick Sedgley, a seventeen-year-old from Essex who makes a single moral choice in a field one September morning in 1939 and spends the next four years living with the consequences. From the Essex countryside to occupied France, from the mountains of Burgundy to the Pyrenees, it is a story about promises, betrayal, courage and the cost of doing the right thing too late.

And for those who have been waiting patiently for the Pendragon Saga to continue: the third book, Shadow's Heir, the story of Arthur Pendragon, follows in September 2026. More on that very soon.

C.M. Gray was born in England and grew up in the Essex countryside near the Suffolk border, which is where Derrick Sedgley grows up, too. The flat fields, the big skies and the particular quality of Essex light found their way into the book, whether he intended them to or not.

C.M. Gray is now very happily settled just outside Barcelona with his wonderful wife and partner in life, Adriana.
