The Determination - Edward Kress

Humanity's war for survival has entered a far more brutal stage.

In They Come From Below and Above: Book Five - The Determination, the invasion is no longer a terrifying mystery or a rising global crisis. It has become a full-scale extermination campaign, and the enemy is pressing harder than ever from every direction. The skies burn with descending fleets. The ground erupts with impossible forces from below. Entire cities collapse in waves of fire, metal, and blood as the planet is dragged deeper into a war no one was prepared to fight.

The survivors of the earlier battles now face an enemy that is evolving in both strategy and cruelty. Humanity is no longer dealing with isolated attacks, scattered invasions, or even overwhelming military defeats. The conflict has become organized, relentless, and merciless. The invaders are adapting. They are learning human weakness. And they are using it with horrifying precision.

As world governments fracture and military resistance begins to fail under impossible pressure, those still standing are forced into a desperate new reality. Every victory comes at a devastating cost. Every defense line is temporary. Every city that still stands feels like borrowed time. What remains of human civilization is running out of places to hide, out of weapons strong enough to matter, and out of time to understand what these beings truly want.

At the center of the chaos are the men and women still determined to fight, even as the world falls apart around them. Soldiers, survivors, and leaders are pushed into battles they know they may not live through, facing enemies that tower over them in strength, intelligence, and destructive power. The cost of survival is no longer measured in casualties alone, but in what humanity is willing to become in order to keep fighting.

Dark, fast, and relentless, The Determination drives the series into even larger-scale destruction, more savage warfare, and higher emotional stakes. Massive alien forces, collapsing cities, impossible enemies, and last-stand resistance collide in a brutal science-fiction nightmare where extinction feels closer than ever.

The invasion is spreading. The war is escalating. And if humanity is going to survive what comes next, it will take more than courage.

It will take determination.
