Graveyard Rules — Gary Cook

When undercover narcs Ben and Barney are brutally worked over by drug dealers, they smell a set-up. Now they're out for justice--and revenge. But beneath the slick maneuvers of these deputy-sheriff partners, beneath their old-buddy banter and clowning, lies a shared experience too searing to remember ... except when sunlight on green leaves looks like camouflage, and Western sunsets run red with blood...

Through the coarse, random violence of Montana's honky-tonks, Barney and Ben track their quarry. And when the beauty of the frozen peaks and clear blue waters explodes in savage slaughter, the ex-Green Beret and the former Marine slip back into the graveyard rules they learned too well in the blood-drenched jungles of 'Nam--kill or die.
