Operation Endgame

The clock has run out.
Admiral Jack Romanoff and his people have beaten the Tardans at DuPont, but they failed to get the master control codes that could have ended the invasion without bloodshed. Now, they have no choice but to confront the enemy at the heart of the Confederation: Earth. One last battle for everything they hold dear.
The midnight hour is upon them.
While the battle for supremacy is fought in space, Lisa Gane and Tina Chen will battle the Poseidon Group on the ground. If they can't overthrow the traitors, humanity will be trapped under their heels. They will do anything to stop their enemies, but will it be enough?
One chance for victory.
With no room for error, they can't afford to leave anything on the table. This is it. The endgame is upon them, and they will either win or perish, and humanity might go along with them. Will they save the Confederation or doom it to oppression and death? This is the day that they must win, or everything they sacrificed will be for nothing.
A single toss of the dice to win everything or fail humanity at the last moment.
