Five years after the events of Infinities Unbound, a portal to the Large Magellanic Cloud has suddenly reappeared. A single starship, the USS Valhalla, is ordered into the distant LMC in search of the missing starship Europa and her crew. Valhalla’s eccentric and politically controversial commanding officer and his eclectic crew have been tasked with discovering the fate of the traitor Sandhurst, as well as that of the Amon and Skorrah species.

A cadet cruise reunites a previously close-knit group of officers as they shepherd a class of young Starfleet trainees on a five-week training excursion. A simulated mission suddenly becomes active duty as a real crisis arises, and both teachers and students find themselves caught in a genuine no-win-scenario.  

The year is 2385 and three Starfleet vessels have disappeared in the Gamma Quadrant.

As the new crew of the USS Challenger prepares for the next phase of their ongoing mission they must overcome the memories of a war gone and the foreboding future at hand ...
