The nightmare should have ended in Mexico.
For FBI Agent Andrew Brush, it was only the beginning.
Still struggling to rebuild his life after a devastating battle with the ruthless cartel leader known as El Diablo, Brush is drawn into a new investigation unlike anything he has ever faced. What begins as a search for answers quickly spirals into a deadly conspiracy spanning continents, buried secrets, and enemies who should have remained in the past.
Far from home and thrust into one of the most unforgiving environments on Earth, Brush finds himself trapped in a world where survival is never guaranteed and trust can be fatal. As old adversaries emerge from the shadows and new threats close in from every direction, a chilling truth begins to surface:
Some enemies are willing to wait years for revenge.
Some betrayals never die.
And some secrets refuse to stay buried.
With the lives of those he cares about hanging in the balance, Brush must confront dangers both old and new in a relentless fight for survival that will push him beyond his limits.
Because the ice remembers everything.
And beneath it, something deadly has been waiting.
