The Deadfall Protocol

Siberia. Minus thirty. A blizzard closing on a research facility no map will admit exists.
Helix Installation 7 was buried in the taiga to hide what the Soviets built and abandoned. Decades later, a black-money programme reopened the site.
Then something broke out.
Five engineered predators. Wolf and bear spliced into something made for the next world. The alpha stands three metres at the shoulder. The locals call them Volkovs. The scientists called them assets.
Neither word will save anyone.
APEX Unit is sent into the storm to contain the breach, recover the research, and stop the creatures before they reach the village downwind. Major Sara Vance has hunted engineered monsters before.
Never one that hunts her back.
The Volkovs aren’t running.
They’re learning.
The lead scientist isn’t dead. She has chosen them. And as the blizzard closes in, Helix becomes more than a failed experiment. It becomes a proving ground.
By the time the snow lifts, five sets of tracks will lead south into the wild.
Each one different.
And one of them stops, just once, to look back.

Deadfall Protocol is Book 1 of The APEX Files, a five-book action-horror thriller series. One team. Five biomes. Five engineered nightmares. One conspiracy with the patience to wait fifty years for the world to fall apart.
