This is a five-volume history focusing on the Anglo-German naval rivalry from its origins in 1904 to the ultimate demise of the Imperial German Fleet in 1919. This is history writing at its epic best.

Marder’s approach to history is even handed and avoids partisanship. His research is monumental is scale and he developed a network of relationships with many of the key figures in the story. The result is an incredibly well researched and informed history of the naval war, with great depth of insight, all written in an approachable style.

A true classic of naval literature that is a joy to read and is unlikely to ever be surpassed.

If there is one story to fire the imagination about naval action in the First World War, it is that of the German cruiser Emden and her crew. Her commander, Karl von Müller, showed skill and chivalrous humanity in equal measure.

Emden raided the Indian Ocean, pursued by numerous Allied warships, causing havoc to commerce. The cruise ended in an epic final action with the Australian cruiser Sydney. Part of the crew then made an audacious escape home across the Indian Ocean and the Arabian Desert.

Lochner’s research is thorough, making extensive use of archive material to tell the story. This is essential for writing well-informed history, but he also brings the crew and their adventures vividly to life.

The remarkable story of the Royal Navy Submarine Service in the First World War deserves greater recognition. This book takes you inside their world.

It tells the story of an action-packed patrol by submarine E.11 into the dangerous Turkish waters of the Sea of Marmora during the Dardanelles Campaign in 1915. E.11’s captain, Martin Nasmith VC, pushed the limits of what was possible to attack enemy warships and supplies, even swimming out to disarm a torpedo that failed to explode in order to use it again!

The book resembles a novel, but the events are entirely factual to the historical record. Nasmith and his crew collaborated closely in the drafting. It is this that gives the book the feel of experiencing the events with them as they unfold.

Successful amphibious operations are hard to pull off. The Allies failure at Gallipoli is well known.

This book tells the story of Operation Albion, the successful German seizure of the Russian islands in the Baltic. A large part of the German Fleet was involved and had to overcome stubborn resistance by the battleships, cruisers, and destroyers of the Russian Fleet to break into the Gulf of Riga.

The Baltic is a little-known theatre of naval operations. The book draws on both Russian and German sources to show how the German Fleet and Army worked hand in hand to achieve a decisive victory in this theatre of the naval war.

Any research into the codebreaking arm of British Intelligence during the Great War will quickly point to one man as the mastermind: Admiral Sir Reginald “Blinker” Hall. He is, at a glance, one of the most intriguing historical figures you’ll ever come across…and the more you learn, the more convinced you’ll be of that. In Blinker Hall, Spymaster, Ramsay delivers not only a thorough look into intelligence and codebreaking, using documents that have been declassified only recently to his writing, but also an insightful look into the man who orchestrated one of the most complex intelligence systems of the modern era. For anyone interested in intelligence, cryptography, or even just the invisible world behind a war that spanned continents, this book delivers it all, and does it in an engaging, entertaining style.

I’d always imagined the femme fatale, Mata Hari, as the female spy of WWI, but in this well-researched book by Tammy Proctor, I was fascinated to learn there were quite a few women agents in the Great War. Proper ladies, in long dress skirts or nurses’ uniforms, each playing her part in a dangerous game of subterfuge against the enemy to help the Allies win. They knew the risks, yet were willing to sacrifice their lives for what they saw as the greater good; and it was these women who inspired me to create the heroine in my book, Evelyn Marche. Her bravery and daring in the novel are a tribute to them.

Read as a teenager, this book hooked me into mystery thrillers. It has everything from murder to political intrigue to a spy ring.

The book is a chase thriller with twists, turns, and surprises. Written in 1930, the work had the feel of a ‘boy's own’ adventure story with a man on the run hunting German spies and clues leading to the 39 steps and victory.

Great story!

British people have often heard of Edith Cavell, who has been commemorated in Britain as a national heroine of the war after she was executed by the Germans in 1915 for her role in running an escape network in Belgium for Allied Soldiers. But Cavell was only one individual amongst hundreds who resisted the authorities in occupied France and Belgium. Like Cavell, young Belgian woman Gabrielle Petit was remembered as a national heroine after her execution during the war. De Schaepdrijver’s book vividly brings her story to life, explaining how she was became involved in espionage, as well as showing how a cult of remembrance grew around her in the decades following the 1918 armistice.

Henry Landau’s story is a favorite because it visualized for me the brilliance of WWI espionage. During the war, Landau worked for the British Secret Intelligence Service in neutral Holland and collaborated with the resistance group “La Dame Blanche” or “The White Lady” in occupied Belgium, who covertly provided him with intelligence to aid the Allies against Germany. They created innocuous “grocery lists” – a code for how many German troops, horses, and artillery were sighted at Belgium’s train stations, and “letterboxes” used to pass intel so as to safeguard each cell of agents from capture. I was thrilled to discover this “White Lady” network of mostly noncombatants—women and children—whose ingenuity in surveillance was well before its time.

Talk about a real-life action heroine! I grew up loving stories of intrigue and suspense, and Marthe McKenna’s 1932 memoir is like reading a thriller! As a young woman in German-occupied Belgium during WWI, she worked for the Resistance right under the enemy’s nose. I felt her fear as she witnessed brutality or took outlandish risks, and her exploits were incredibly brave for a woman of her time. I was in awe to read the book’s foreword by Sir Winston Churchill himself, lauding Marthe’s extraordinary courage and ingenuity during her ordeal. She taught me that we can all do more than we ever imagined if it means our survival, and her story inspired the high stakes I created in my novel.
