In the midst of World War Two, Enigma codebreaker Alan Turing is on the brink of a discovery that will allow messages to be sent into the recent past. When his invention successfully averts disaster on D-Day, the danger it poses in the wrong hands becomes terrifyingly clear. As Turing’s enemies close in, he makes one decision: Nautilus must be kept hidden from the world, safe in the care of the only person he can trust.
Seventy-five years later, Annabelle McIntosh’s life is upended when she learns she will become the latest custodian of the greatest secret of the modern age—Turing’s Nautilus machine. Following in her family’s footsteps and bound by Turing’s strict principles governing the use of his creation, Annabelle is soon faced with the same impossible choices.
Weaving together past and present, The Turing Protocol honors Alan Turing — a genius who was misunderstood and persecuted by his own time — and takes the reader through pivotal moments in history, including the Cuban Missile Crisis, the dissolution of the Soviet Union, and 9/11. All of this leads to the present day, where Annabelle must prevent major catastrophe—but when the stakes are at their highest, is using Nautilus the perfect solution or a risk too dangerous to take?
A riveting speculative historical suspense debut told in alternating timelines. Will the most powerful invention in history save the world—or destroy it?
