Plot summary
As a former staffer at the Environmental Protection Agency, Jack McDarvid, the main character, knows all about extremists in the cause of virtue. He now works for a law firm that represents companies that need clearances or information about just what is or is not allowed. But then his boss is killed in a shootout near the Capitol, and nothing is what it seems. And no one what they appear to be.

From Moscow to Washington, from a near hit and run to the very real threat of a nuclear time bomb in the hands of a fanatic with a point to prove, The Green Progression moves non-stop through the machinations behind the scenes of the environmental movement.
