The Dyson Sphere Odyssey

Now that wormhole space travel is mastered, a special organization, called, Space Planetary Recognizance, is formed to disperse recognizance teams all over the galaxy. Each of the twenty teams, during a three year period, is sent to visit and catalog several planets found by the space telescope, Copernicus.
The team led by Gabe, and with his partner, Ralph, discover there are more stranger worlds in the galaxy than they can imaging. Their ultimate discovery is a construction that humans only contemplate.
