The books depict a dystopian future, set in a hypothetical mid 21st century where a new Russian Soviet has invaded Western Europe, causing massive disruption and destruction.
Their armies were only repelled by the (unseen) use of tactical nuclear weapons, resulting in a stalemate, somewhat like the middle years of World War I.
The heroes of the series are the New Resistance, who are fighting to expose and defeat the SA's racist policies and the neofascist attempt to grab power.
The scope of the story is worldwide, but the main action mostly takes place in Europe, on a small Caribbean island and on humanity's first space colony.
"[1] An updated, re-edited version[clarify] of the trilogy has been released by Dover Books, starting with A Song Called Youth: Eclipse, in October 2017.
