Primal Unleashed — Jack Silkstone

The mission began, in 1989 Afghanistan, when a Russian platoon battled Afghan warriors -- and raced to bury forever a devastating secret worth the greatest sacrifice. It could end apocalyptically, in the present, if a sinister evil escapes its sealed tomb…into the hands of one of the same men who fought to bury it.

Intel suggests that's exactly what's happening: A Ukrainian veteran of the '89 Soviet-Afghan conflict, battle-scarred and cold-blooded, is now a wealthy businessman -- with a sideline selling deadly hardware to the highest bidders. He's getting ready to make his biggest deal yet with a radical Iranian commander hell-bent on possessing the ultimate doomsday weapon. Only the battle-tested skills, state-of-the-art tech, and no-rules-but-their-own attitude of covert vigilante strike force PRIMAL can keep bloodthirsty madmen from unleashing hell on earth.

PRIMAL deals unconditional justice -- with cold steel -- to a world in dire need of heroes.
