To save her mother, Harper Knight must stop the moment that doomed humanity.
In 2101, the population lives in isolated encampments under strict control. Leaving is not an option. Anyone who tries is executed. Decades earlier, a technology known as the Voice of God infiltrated human thought, unleashing chaos and fear that reshaped the world and drove the population into containment.
The system was not an accident. It was built to last.
When Harper’s mother disappears into the timestream to stop its release, Harper follows.
With the help of her brilliant and loyal friend Lark, she travels across centuries and dimensions, from modern-day New York to the Hanging Gardens of Babylon and into the unstable realm known as the In-Between.
But the past is protected.
Time Travel Bureau agents hunt her across history, determined to preserve the world that rose from that single moment. Every step she takes brings them closer.
If she fails, humanity remains exactly as it is. Afraid. Controlled. Contained.
