What if the greatest weapon of World War II never disappeared—only went underground? For fans of Dan Brown, Matthew Reilly and Fiona McIntosh comes a pulse-pounding historical thriller where one invention could rewrite the fate of humanity itself.
During the darkest days of World War II, brilliant codebreaker Alan Turing creates Nautilus: a secret machine capable of sending messages into the past. When a single message helps secure victory on D-Day, Turing realises the terrifying truth—history can be changed.
But every alteration comes at a cost.
Knowing the machine could spark catastrophe in the wrong hands, Turing entrusts Nautilus to Joan, the mother of his hidden child, binding his family to a dangerous secret that will span generations.
Across seventy years of war, betrayal and impossible choices, each heir to the Turing legacy must decide when—or whether—to use the machine’s power. A whispered warning could save millions. A single mistake could unravel the world.
Because once you can change the past, the future is never safe.
Genre: Science Fiction
