What does it mean to be human? What if the price of saving humanity is giving up your own?
The year is 2322, and we stand upon the precipice of extinction. The invading Metigen armada has decimated the eastern third of settled space in a matter of days, leaving tens of millions dead. Determined to save the heart of human civilization, Earth and Seneca at last put aside their differences to face the threat together. But even this may not be enough to stop the fleet of colossal dreadnoughts inhabited by advanced AIs.
Alex Solovy and Caleb Marano hold the key to defeating the invaders, for they know the secrets the aliens wage war to protect. Now they face a deadly gauntlet of relentless alien hunters and assassins sent to kill them before they can unleash a potent new weapon. They will risk everything in a bid to save their families, their loved ones, the entire human race--even if it means they can't save each other.
The lines blur between man and machine, ally and enemy, and soldier and civilian. In a final stand against an ancient, powerful foe intent on eradicating it from the universe, humanity comes face to face with its destiny.
