Watcher of the Skies

As an artificial Human, Mike Christopher became the target of hate and prejudice all his life.  He fled the Earth to explore the galaxy.  Still, decades later, he returned to help save his homeworld from an alien incursion.  Now the lifelong explorer once again feels the pull of the stars.  But more immediate concerns still bind him to the Earth.  He finds himself aiding another alien race in its own battle to survive, beginning a new love affair, and learning the tragic details of his own gestation and birth.
In an instant, Mike is torn between his commitment to his birth planet and once again becoming a WATCHER OF THE SKIES.
