When the relentless Grath Armada descends without warning, human civilization is stripped bare in hours. Millions are swept into orbital harvest carriers, categorized like cattle, and frozen for consumption by an empire that knows no restraint. To the predatory Grath, humanity is nothing more than livestock, crying the helpless food cries of easy prey. But they underestimated the weapon they came to harvest. Led by Millard Sterling, an analytical structural engineer who understands how things hold under pressure, the captive humans begin to adapt, resist, and push back. In the cold expanse of the void, the hunted become the apex predators. The Tarryn Directive is an adrenaline-fueled military sci-fi thriller exploring humanity's brutal resilience when pushed beyond every imaginable limit.
