Echoes of Esharam

He only wanted to go home, but first he must save humanity. . .
Delivered at last from the hell that was Bera Nima prison, Darrien Norris basks in a freedom he thought would never arrive. But as he waits for the Transceptor to restore his memories from seventeen years before, he discovers an alien race intent on destroying everything, and everyone, in its path.
Now Norris and his friends must devise a plan in a desperate mission to prevent a galactic catastrophe. Will they succeed? Or will humanity cease to exist-forever.
