Galactic Passages - Dean Vargo - Bog

This is a science fiction adventure about how progressive hunger for wealth and power within a society [Planet Raihan] have resulted in duping other planets into mining valuable ore for them amidst the orbital hazards of Planet 6333. They have severely hurt other cultures along the way; raising themselves galactic prominence through manipulation of the relationship between a planet loaded with valuable ore, and a dimensional portal caught in a gravitational tug-of-war between two suns.
From the beginning, remote miners are steadily shut off from communicating with their home planet through Raihan manipulation from a secret base located on a nearby moon; eventually feeling neglected and alone just as Planet 6333 enters the dangerous portal zone in the midst of its orbit. The victims ultimately see the Raihans as rescuers rather than kidnappers when they come in the midst of planetary chaos to steal the ore and take them as hostages.
When examined closer, the Raihan culture is a paper tiger, dissolving from the inside out due to their evil ways. Circumstances arise that allow two smaller planetary forces [the Trecons and Ryderson-Omegans] to band together and challenge the Raihan goliath; but they can't do it alone.
The story ends with a surprising twist, and points toward future adventures!
