The Vengeance of the Tau — Jon Land

TERROR
An epidemic of violent death is sweeping the globe. From the Middle East to the Midwest, from South America to the Deep South, a mysterious power is forging a trail of butchery.

TREACHERY
Blaine McCracken--former government agent turned international troubleshooter--is hot on the trail of whoever, or whatever, is behind the slaughter spree. He's as ruthless and resourceful as they come when battling evil. But he may have met his ultimate match in an enemy that's always one step ahead.

TERMINATION
From the distant past, a conspiracy born of vengeance has returned--and from the depths of the earth it has brought forth its instrument of annihilation. But the violence done is only the bloody beginning of the violence to come, in a conspiracy that could push humanity toward an unspeakable end.

THE VENGEANCE OF THE TAU
Facing worldwide death squads, Blaine McCracken and his small band of allies are pitifully outgunned. The name of the game is kill or die--and they have no choice but to play.
