Military Space Opera

Humanity's thousand-year-old interstellar empire has been rotting from the inside for over a century, thanks to venal, corrupt, and power-hungry sovereigns from a dynasty many consider illegitimate. The latest in that lineage, an increasingly psychotic empress, is pushing her realm toward collapse as admirals and generals rebel against her rule. That rebellion quickly drags the once mighty Imperial Fleet into a devastating fratricidal conflict between factions.

Already uncertain about her future in the Jedi Order, Iskat faces tragedy when her master is killed and the Clone Wars engulf the galaxy in chaos.

The Federation's military command is desperate, and with their fleet still in tatters, they make a last-ditch effort to free the planet: They pull Captain Jackson Wolfe out of retirement and put him in command of a ship they hope can get past the defending armada and provide support to the beleaguered Marines and civilians fighting on the surface of the contested world. There is no reasoning with this enemy. If the Terran Federation wants their planet back, they will have to pay the price.

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

A dirty deal was struck. Humanity was allowed to keep 300 rebellious worlds. In return, we declared war on a powerful enemy from beyond the frontier. A frantic build-up of forces has begun, but the task is hopeless. Seeking allies, Earth's legions are sent to Blood World.

Humanity pushed its way to the stars—and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild.

And because they do, they know the penalty if they lose will be far worse than their own deaths and the destruction of all they know and love.
