Jack Munroe’s anti-predator crusade is stopped cold by an ultimatum from the Arbitors of the Great Dark. Either stop contacting juvenile star systems with his message of liberty and freedom, or humanity will be cut off from the universe with an Isolation Globe that nothing can penetrate! The Arbitors resemble Tyrannosaurus rex dinosaurs. But these dinos have giant spaceships, a shield that blocks all energy weapons and they view Humans as upstarts who must either play by their Rules, or be blocked from ever again exploring the stars. With the help of his physicist buddy Archibald and the battle skills of Maureen, the deadliest grandma in space, Jack sets out to use Dark Energy as a covert weapon to kill both the Isolation Globe and the weapons shield of the Arbitors. Doing that demands wild Tech and the American Can-Do spirit that is the heart of Asteroid Belt society. But will the final showdown lead to victory over the dinos, or leave humanity Isolated from the stars?
