The Turing Protocol imagines an alternate history in which Alan Turing creates a machine capable of sending messages into the recent past. After using it during the Second World War, Turing entrusts the invention to Joan, the mother of his secret child. The device is passed through the Turing family over several decades, giving successive generations the power to alter history. Their choices create consequences that could either save the world or destroy it. The novel combines historical fiction, time travel, espionage and speculative science.
