The Star Alliance Chronicles: Crisis on the Rim

In a remote sector of space, there are dangerous enemies waiting to strike at the heart of the Galactic Coalition of Worlds. They can attack without warning and show no mercy, and they will destroy all who dare oppose them. Some possess technologies so advanced, they can suddenly appear anywhere in the galaxy and overrun defenseless planets with ruthless efficiency; others scheme to harness the natural resources of other star systems and enslave their populations.
Despite the Coalition's best efforts, the political stability of the Quadrant continues to deteriorate, with enemies of the alliance challenging its sovereignty, launching raids of territorial conquest, and engaging in costly, punitive wars. As peace slowly takes hold of the Quadrant, a new, even more powerful menace is discovered by the crew of Base Station DD-109, a sprawling outpost located near the galaxy's rim, on the very edge of Coalition space.
This station is not a typical Coalition Command base. It is not blistering with the latest armaments nor does it boast an array of powerful starships. DD-109 is a Coalition salvage yard, its only function to decommission and dispose of wrecked, outdated ships and their technologies. Dark, dirty, and literally weeks away from the nearest base station, it is also a place where some Coalition fleet commanders send their most difficult and troublesome personnel cases.
It is often said to be a place where both ships and careers go to die. Nestled between the Borias and the Lehar Star Systems, and with no defensive capabilities, the base has become a tempting target for those who have been studying that sector as they prepare to strike at the Coalition. Unknown to its personnel, Base Station DD-109 will soon hold the key to the future of humanity and the entire Quadrant.
With no hope of assistance, armed with only antiquated and makeshift weapons, an untested crew of officers, engineers, and maintenance workers from DD-109 will confront a lethal invasion force from the rim of the galaxy. Their mission: hold the Lehar-Borias System and deny the enemy access to the base station. If they succeed, they will save the lives of billions of Coalition citizens; if they fail, their enemies will unleash a ruthless intergalactic war of extinction-an apocalypse.
