Eclipse Penumbra — John Shirley

The guerilla war against the Second Alliance and its plans for a European apartheid intensifies in this second volume of John Shirley's A Song Called Youth.
"Almost anyone could be a fascist under the right circumstances. If they get scared enough. That's why we have to fight it so hard. Because it never quite goes away."

The penumbra of the Eclipse it would establish complete SA control over the Grid, the space colony and the survivors of the war and decide the fate of humanity itself.
