'Black Jack' Geary has ordered his fleet back to the Lakota star system where the Syndics nearly destroyed them, a desperate gamble that may give them a fighting chance of survival - or tear them apart.

After freeing Alliance POWs, 'Black Jack' Geary discovers that the Syndics plan to ambush the fleet with their powerful reserve flotilla in an attempt to annihilate it once and for all.

As war continues to rage between the Alliance and Syndicate Worlds, Captain 'Black Jack' Geary is promoted to admiral - even though the ruling council fears he may stage a military coup. His new rank gives him the authority to negotiate with the Syndics, who may finally be willing to end the war. But an even greater threat lurks.
