Some echoes never die.
When a ghost signal crackles out of the Siberian tundra, it doesn't just trigger a mission-it unearths a ghost. Rowan "Red Echo" Wilder was presumed dead after a black ops mission went wrong. But four years later, he's still alive-feral, hunted, and alone in one of the most hostile landscapes on Earth.
Leon is the one sent to bring him back. Tactical, composed, loyal to the team that once left Rowan behind. But what begins as a mission of extraction becomes something far more dangerous: a fight to stay alive-and a reckoning with everything they never said.
As bullets fall and secrets rise, two men must decide what survival really means when the world no longer wants them back.
In this emotionally charged installment of the Shadow Unit series, Red Echo delivers slow-burn intensity, wilderness tension, and the kind of love that refuses to disappear-even when everything else has.
