For an assassin, the past is the deadliest enemy of all...

Betrayed and left for dead, Caine is hiding off the grid in Pattaya, Thailand. But when human traffickers target a woman Caine swore to protect, the vengeful assassin wages a bloody one-man war to get her back.

Facing off against the Thai underworld, a jungle militia, and an insane criminal warlord, Caine will stop at nothing to save his friend.

But when the trail of bloodshed leads to the frozen wasteland of Siberia, Caine finds himself hunted by a crack team of Russian mercenaries, led by a brutal Spetsnaz commander.

From sweltering jungles to a frozen lake, Caine unleashes hell on anyone who gets in his way. For years he's kept his deadly instincts locked inside. Now, the killer has been set free. And his enemies have no idea what's coming for them...
