Crippled Earth — Maquel A. Jacob

The alien enemy launches the first strike ahead of schedule, starting a bloody, drawn out war. Humans, Karysilans and rogue Relliants join forces to defend Earth. The outcome isn't looking in their favor. Out of fear and desperation, all the players initiate their own agendas while the facilities seal themselves off; refusing to engage in the fight, infuriating Captain Darnizva. He's tried to unite humanity for half a century and now realizes it was all for nothing. With no word of reinforcements from his home planet, Mankind's extinction seems to be imminent.
