From publisher blurb:
War has finally come to the Sonora sector. After many proxy wars and minor skirmishes the Olonsean Empire and the Ilsunsi Directorate are actively engaged in hostilities. The battles have been fierce and bloody and both sides have taken extensive losses in the fighting. The Olonsean Empire has begun issuing Letters of Marque to ship captains interested in attacking or capturing Ilunsi vessels for profit. One need only put in to port at an Olonsean system and request an audience with the local Naval commander to ask for such a letter.
Other governments in the Sonora sector have remained silent about this development. The legal authorities in the sector seem to have decided to take no side in the matter to avoid being dragged into the war themselves.
A daring ship captain or crew could potentially make a lot of money while the fighting goes on.
