The Gael Gates - Galactic Adventures, #2

The Federation is on the verge of collapse. After three people disappear into the mysterious portals that hold the empire together, Culann Penrose is called in to investigate. After he discovers that the ancient gate system is crumbling, he orders them to be shut down. The druids oppose Penrose's plans, and soon, Culann discovers that something is out to destroy him, and plunge the Empire into an age of darkness.
Can Culann's Science save Magic before it destroys him, or will his Magic save the Science of the Gael Gates?
