Greater Glory of God

Earth barely survived the 21st Century.
Thousands fled the chaos on rogue warpdrive ships to settle colony planets. When Earth reunified in the 22nd, its fleets rediscovered the colonies and hunted down the warpdrive ships.
Every warpdrive ship but one.
Undercover on Trinity, Stone and his unwanted partner must earn the trust of religious fanatics who will stop at nothing to find the last warpdrive ship. A ship that, if sent on a suicide mission, could devastate Earth.
A ship, but who will fly it?
