In Public Convocation Assembled - Stone Chalmers, #4

One man can make-or break-Earth's iron grip on its galactic colonies: Stone Chalmers. Spy. Assassin. Earth's top operative. Schemes and plots from the colonies and the capital converge in the halls of power on Earth itself. Stone's mission: make contact with Earth government officials of questionable loyalties. Feed them false intelligence. And at the right moment, strike. Though undercover and disguised by nanotechnology, Stone knows this will be his toughest mission yet.
One mistake could doom Earth and the colonies to centuries of tyranny. Though Stone has allies, Earth's top operative alone can fight his way through a web of intrigue and bring freedom to all human worlds. Join Stone in the capital of the galaxy for the ultimate clash of conspiracies in this, the final adventure in his complete four-novel series.
