Space Fury

Blake had waited a long time for his big chance. Finally the selection board called him in. This was it. He got his promotion, his captain's ticket and his first assignment. Vorgal was a tough planet but Blake was ready for it. He was the first spaceman to land on Vorgal without crashing. He was the first human being to see a Vorgalian and live. He was the first to learn the planet's deadly secret an come back alive. But...when he went into landing orbit around Earth they fired on him. No one would believe that the impossible had happened. They thought Blake's body was being used by an alien, and unless he could convince them fast he would die. Without his secret knowledge of Vorgal, Earth would die too...
