From the introduction:
Darkening Skies over the planet of Haven. An Imperial warship, half-metre long and heavily armed, lies still and unresponsive. Her shadow falls across continents. The Trade Union are spooked. They'll blow the ship to pieces; try to forget it ever existed. But there were people on that ship, soldiers and prisoners, and enough weaponry to equip an army.
So a rag-tag band approaches the ship in a cheap and collapsing boat. One searches for friends, another for adventure. One looks for love and one looks for profit.
One looks for answers.
