Harvest: Retaliation

Five years after humanity survived the Harvest, the warning comes again.

The enemy has not forgotten Earth.

When Vengeance detects new signals in deep space, Daniel Mercer and the crew discover that the Harvesters are returning—and this time they are coming for retaliation.

But something far more dangerous is moving through the darkness behind them. An ancient force powerful enough to threaten not only humanity, but the civilizations that have watched over Earth for thousands of years.

Old enemies may have to become allies. Ancient weapons will awaken. And humanity must take its place in a war that began long before the first humans looked toward the stars.

Earth survived the harvest.

Now comes the retaliation.
