The human race is running out of time on overcrowded Earth, and only one man has the courage to do what is necessary to save it. Colony ship Ark is the greatest project the human race will ever attempt, a self-contained world one hundred years in the building, launched on a ten thousand year voyage to carry the seeds of civilization to the stars. It is humanity's final gamble for escape from a desperate world, but the price of hope is measured in lives.



Joshua Crewe, Ark's designer. Obsessed with his vision, he's devoted his life to winning the power to turn it into reality. No burden is too great to bear in pursuit of his dream—especially when other people are the ones to bear it.



Aurora Brady, first of the space-born, with one foot in the future and one in the past. She must give power to her enemies to see Ark launched, but giving too much will mean its destruction.



Jedidiah Fourgere, a simple farm boy. He finds himself caught up in a revolution that will forever change the balance of power in Ark's hermetically sealed world. Torn between love and faith, humanity's future lies in his hands.
