For over 30 years, there has been no word or sign of the Zaltule. The Zaltule are the warrior caste of the Kleese and the most dangerous race in existence. In a battle that nearly destroyed the solar system, the Zaltule were driven from human space. Now, they are back and more deadly than ever. If they are not stopped, the humans and their allies will be destroyed or forced into slavery.

Thomas Nelson is a corporal in the Marines. For years, his family has been one of the leaders in protecting the human race and leading the fight against the Kleese and the Zaltule. Now, it is his turn to do what his uncle and father have done. Find a way to save the human race from destruction. 

Admiral Kelly has come up with a daring plan to end the Zaltule, once and for all. It’s up to Thomas and his Marines to accomplish the impossible. If they fail, it will be the end of everything.

Massive battles erupt across space as the Zaltule return. Fear encompasses the Alliance as they see their worst nightmare become a reality. Led by the humans, a desperate mission is launched to save everyone from destruction. Unfortunately, the mission has little chance of success.

But even a small chance of success is better than none...
