Now in one volume, the first three books of John B. Rosenman's Inspector of the Cross series.

The Cen, a cruel alien race, has attacked humanity and only one man can save it. Turtan, an Inspector of the Cross Empire, travels in suspended animation to distant worlds in search of a weapon or device that can defeat the enemy and end the brutal five-thousand-year war. Because he travels in frozen sleep, this elite agent is technically four thousand years old and has outlived many lovers and generations of his children. It is a painful and terrible burden, but duty comes first and always he must move on. His mission is rendered even more difficult by his own leaders who sometimes oppose his selfless quest to save humanity.
