The Greater Glory of God - Stone Chalmers, #2

One man can make-or break-Earth's iron grip on its galactic colonies: Stone Chalmers. Spy. Assassin. Earth's top operative. From the religious colony world of Trinity come clues of a long-lost prize. The last warpdrive ship outside Earth's control. Stone's mission: journey through an artificial wormhole to the planet. Verify the reports. And if the ship exists, prevent its use by Earth's enemies. Going undercover, with a cover persona overlaid on his mind, the only thing holding him back is an unwanted partner from a rival agency among Earth's rulers.
Then he finds rich and powerful colonists hunt the missing ship for their own nefarious purposes. A ship that could devastate Earth in a suicide mission. Or worse. Join Stone in a nerve-wracking game of intrigue on a world of secrets in this, the second adventure in his complete four-novel series.
