GUARDIANS OF THE GALAXY The onslaught of the Melconians was not the last conflict that humanity's interstellar Concordiat would have to face. For now the Kezdai -- a newly encountered species with war at the center of their philosophy -- have taken to arms against the Concordiat and its colony worlds. For war, the Terrans have only one answer: Break out the Bolos Self-aware robotic tanks, the Bolos have fought bravely and well since the days when humans fought each other. Now they battle across the stars to defend us all...and though the times are perilous, we've never been in better hands than those of our old metal guardians: Keith Laumer's greatest creation, the Bolos.
