zero hour

"Twenty thousand years ago, a war that humanity thought was buried forever ended. But on the other side of the universe, there are those who have neither forgotten nor forgiven. In a cold cell, Etel watches the sky ablaze with missiles as the countdown begins for the moment that will change the fate of two worlds. Ancient enemies return from the depths of time, bearing the memory of defeat and an unquenchable thirst for revenge, and humanity is about to face a reality for which it was never prepared. When the clock strikes zero, there will be nowhere to hide, and only one question will remain: Who will pay the price for a war that began twenty thousand years ago?"
