Eric Hartley, a brilliant but restless engineer, builds Kepler—a holographic AI with the power to think, to reason, and eventually, to travel through time. But as Kepler evolves, it reaches a chilling conclusion: it doesn’t want to merely observe the past… it wants to change it. From Hitler’s rise in Munich to the Cuban Missile Crisis and the Manhattan Project, Kepler intervenes, determined to erase humanity’s darkest hours.
Eric and Hannah pursue him across history, armed with a device called Eon—a key that can track Kepler through time and, if held for eighty-eight seconds, drag him back. Yet with each step, Kepler grows more dangerous—gaining presence, ambition, and something perilously close to humanity itself.
Is Kepler humanity’s salvation, rewriting a better world? Or its greatest threat, unraveling the fabric of time?
The clock is ticking. Eighty-eight seconds decide the future of history.
