Beyond the Galactic Core: In the Image of Gods, Book 2 (Unabridged‪)‬

This action-adventure is set during an interstellar war. A secret agent discovers a war inside the war. This sets off a race to acquire alien technology. 

The interstellar war between mankind and the Qwelleron Empire had entered its 10th year. It was only a matter of time before the monsters' full force would be brought to bear and complete the conquest. Then the existence of a new alien race is discovered. The rumors were of possibly extinct creatures who possessed super technology. It was a shadow race in the image of gods. 

Believing it was their only hope for survival, a starship sets out to find the homeworld of these mysterious beings. Their only clue is a story about a girl who, 10 years earlier, had found one of their artifacts. With it she had defeated entire battle fleets. If they could find her they might be able to save the human race.
