Welcome to Outcast Station 

Even outcasts deserve a shot at redemption.

The Accidental Plague by Jeanne Adams 

Outcast Station is a backwater, but for BVax Scientist Ravinisha Trentham, any posting is better than washing dishes. Ravi is top in her graduation class, but only Outcast would hire a McKeonite. Someone on the station wants her dead, but when a plague breaks out, Ravi may be their only hope. If the murderer gets to her first, everyone will die. 

The New Badge by Nancy Northcott 

Deputy Marshal Hank Tremaine crosses the wrong person and lands at Outcast Station, the armpit of Terran space. His hostile boss promptly assigns him to a backcountry murder. Solving it will help redeem his reputation and get him posted somewhere more civilized. But failing to find the killer will bury his career once and for all.
