To See the Evening Sky

The events are current to the world as we know it.
This adventure involves three alienated engineers heading for the reconstruction effort in Puerto Rico. Each man has been damaged by life, which changes dramatically as their small aircraft collides with the off-world activities of a secretive alien race. This human society will remain a mystery but will offer each man a new chance at life.
A subterranean alien civilization has been living and mining beneath the earth’s crust for over 700 years. Though separate from the surface humans, on occasion, the two worlds collide.
