Hunter's run / Martin, George R. R

Ramon, a drifter who escaped the poverty of the Third World by joining an expedition to the distant planet of Sao Paulo, is forced to escape into the wilderness after he commits a high-profile murder, and stumbles upon a highly evolved alien race also trying to hide from the rest of the world.

After awakening in the uncharted mountains of the planet of S?o Paulo with no memory of his identity, Ram?n Espejo experiences flashbacks of scenes from his past that reveal that he is being hunted by mysterious alien overseers.
