The Light of Another Sun — P. Stanley

The Children of Sol is a science fiction epic adventure that weaves the tale of humanity's first attempt to establish a human colony on an Earth-like world in a solar system far beyond our own. A mixture of biblical and mythological themes along with realistic high technology fleshes-out this series and introduces us to a great but very flawed man named Saul Blackwell, who, like many of us, is afraid to die.

The egotistical but brilliant Dr. Saul Blackwell is a pioneering astronaut who seeks nothing less than the very key to eternal life, and while on the shores of an alien world, amongst a primitive alien people, Saul will be confronted with the knowledge that attaining physical immortality may very well cost him his immortal soul.
