Critics Review

‘What sets the book apart isn’t just its concept, but how it uses that concept to explore modern questions: the responsibility of technology, the moral grey zones of war, and the personal cost of carrying knowledge that could shift the future … Whether you’re into alternative WWII fiction, speculative thrillers, or just looking for a smart weekend read, this is one to check out.’ * Write Finance *‘I had a blast inside Croydon’s no-higher-stakes alt-20th-century playground. A wildly imaginative distortion of deeply researched historical fact forming a ripping tale of ‘past careens into present’ fiction. Urgent morse code message to my past self: READ THE TURING PROTOCOL NOW.’ – Trent Dalton‘A remarkable debut novel from Nick Croydon. A smart, gripping thriller with an amazing big idea behind it. I loved it and I can’t wait for the movie and the sequel.’ – T.J. Newman‘An incredible debut thriller where the past can be changed to save the future.’ – Don Winslow‘A thought-provoking alternative history. The Time Machine meets The DaVinci Code.’ – Chris Hammer‘Vivid, tense and sharp – Croydon’s concept will leave your mind and morals delightfully tangled.’ – Candice Fox‘A fascinating alternative history with an intriguing ‘what if’ at its core. A great read.’ – Dervla McTiernan‘An intriguing mix of extraordinary fact and tense fiction’ * Sunday Telegraph *‘Absorbing romp.’ * Good Reading *‘The Turing Protocol is as thought-provoking as it is entertaining.’ – Meredith Jaffe
