The final chapter of humanity's future has begun. Now its only witness, Nigel Walmsley, marooned in a space time anomaly, recalls Earth's desperate struggle against the mechs, the murderously violent artificial intelligence dedicated to the total annihilation of organic life.
Humanity's last tattered remnants have taken refuge in the Esty, a strange continuum, and now only three generations of men stand between the mechs' march of destruction and total oblivion for the human race. Toby Bishop, his father Killeen, and his grandfather, long believed dead but now mysteriously returned, are life's last hope as the flame of human history flickers towards extinction.
