John Twelve Hawks, bestselling author of The Traveler, returns with a masterful journey through the near future of Artificial Intelligence, in which a wise, orphaned ten-year-old girl goes on the run with only her trusty 'Interactive Toy' to guide her toward New York City, where a dark landscape, and perhaps a hidden hero, await her.

As long as she can remember, ten-year-old Kate has felt like someone was watching her. She has been orphaned since the pandemic, her foster parents find her eccentric and off-putting, and her legal guardian is nowhere to be seen. Now, an algorithm has predicted the very worst—​within thirty days, Kate will either be killed, or become a killer. When two police officers arrive at her home in Maine intending to implant her with a tracking device, Kate is urged by her trusted AI Interactive Toy (a talking stuffed seal named Zeno) to make an immediate escape. Confused and looking for answers, Kate sets a course for New York City and begins an Orwellian journey into the unknown.

Gripping, intricately plotted, and delightfully imaginative, Certainty is a profound and eerily prescient novel about the ever-blurring line between man and machine. Amid the murder investigation of a gifted AI robot-maker, a missing-person being tracked down in the darkest corners of virtual reality, and Kate's harrowing journey to New York, John Twelve Hawks's novel explores the spectacular humanity to be found in a world where humans are themselves endangered.
