The Galactic Federation is confronted by the vast and implacable Thandol Empire, which has coveted the former Krall region of space for eons, a region of space now occupied and claimed by the upstart Kobani. Outnumbered, they face an opponent who possesses new and deadly weapons. An enemy that had thousands of years to develop the means to take on the Krall Empire, and now present the supermen with a weapon that turns their greatest genetic asset into their greatest weakness. The new Federation must find a way to survive the most powerful threat yet to their existence. Once again, the Kobani are between a rock and a hard place, poised on the brink of death and destruction.
