The Hidden War: Book one of the Terran Empire Series

Humanity was never supposed to survive long enough to reach the stars.

Six hundred years ago, alien observers looked down on medieval Earth and saw only violence, war, and a species too savage to ever become more than a planetary threat. The verdict was simple:

If humanity ever advanced far enough to threaten the galaxy… they would be exterminated.

Now the Compact has returned to carry out that sentence.

Alien warships descend from orbit without warning. Cities burn. Governments collapse. Across the world, humanity is pushed to the edge of extinction by an enemy armed with overwhelming technology and absolute confidence.

But the invaders made one catastrophic mistake.

They came prepared to fight the humans of the twelfth century.

Instead, they found modern Earth.

Former Marine Daniel Walker wanted nothing more than a quiet life in the mountains of southern Oregon. But when alien hunter units begin sweeping through the valleys, Walker is forced to build something he thought he left behind long ago:

A resistance.

With scattered survivors, hunted civilians, a downed Air Force pilot, and captured alien weapons, Walker's small band begins striking back from the forests of the Pacific Northwest. Every ambush teaches humanity something new about the enemy.

And every human victory teaches the aliens something terrifying about Earth.

But the invaders are not the only predators hiding in the dark.

As the war spreads through the mountains, ancient forces long concealed from humanity begin to emerge from the shadows—watching the invasion, studying the resistance, and deciding whether mankind is worth saving.

Because Earth was never as defenseless as the galaxy believed.

And the real war is only beginning.
